Re: [Scilab-users] The numderivative function
Hello Hermes, If you're using Scilab 6.0.0 the function numderivative is in the differential_equations module so you should use: exec(SCI+"\modules\differential_equations\macros\numderivative.sci", -1); If you want your script to be compatible with both versions you can add: v = getversion("scilab"); if v(1)<6 then exec(SCI+"\modules\optimization\macros\numderivative.sci", -1); else exec(SCI+"\modules\differential_equations\macros\numderivative.sci", -1); end Best regards, Paul Paul BIGNIER Development engineer --- ESI Group - Scilab 99 rue des Solets - 94513 Rungis, France Phone: +33.1.41.73.58.77 https://scilab.io https://esi-group.com From: users <users-boun...@lists.scilab.org> on behalf of Hermes <herozi...@gmail.com> Sent: Monday, November 20, 2017 10:50 AM To: users@lists.scilab.org Subject: Re: [Scilab-users] The numderivative function Hi, When I execute the command: exec(SCI+"/modules/optimization/macros/numderivative.sci",-1); I get the following Scilab alert: exec('C:\Draghilev''sMethod_4.sce', -1) at line14 of executed file C:\Draghilev'sMethod_4.sce at line -15 of executed file C:\Draghilev'sMethod_4C.sce exec: Cannot open file C:\PROGRA~1\SCILAB~1.0\modules\optimization\macros\numderivative.sci. the command is inserted in the script before calling the fumciont ode. it is right?

[Scilab-users] Scilab 5.5.2 on macOS High Sierra
Hello Mac users, As Scilab 5.5.2 requires a Java 1.5 install, we need to make it think it has one. Here are steps to run Scilab 5.5.2 on High Sierra: * open a terminal (found in Applications -> Utilities -> Terminal) * note the path returned by: * /usr/libexec/java_home * in my case it returns /Library/Java/JavaVirtualMachines/jdk1.8.0_102.jdk/Contents/Home so in the following commands, replace it with your path. Run the following commands (you'll need sudo rights): * sudo ln -s /Library/Java/JavaVirtualMachines/jdk1.8.0_102.jdk/ /System/Library/Frameworks/JavaVM.framework/Versions/1.5 # Make Java 1.5 point to our install * sudo mkdir -p /bundle/Libraries * sudo ln -s /Library/Java/JavaVirtualMachines/jdk1.8.0_102.jdk/Contents/Home/jre/lib/server/libjvm.dylib /bundle/Libraries/libserver.dylib # Make the requested libserver.dylib file point to our libjvm.dylib * if you get 'Operation not permitted' errors then please consult http://osxdaily.com/2015/10/05/disable-rootless-system-integrity-protection-mac-os-x to bypass macOS protections * at Scilab startup, click on Try Anyway when asked about the macOS version * if you're asked for Java6, follow the steps described at http://www.scilab.org/en/download/latest Regarding Scilab 6, it is recommended to wait for the next Scilab release which simplifies the launch on High Sierra. Otherwise you may refer to http://bugzilla.scilab.org/show_bug.cgi?id=15307 for a workaround.

Re: [Scilab-users] Xcos Coselica blocks - Error while running - C compiller
Hello Gnu, To run Xcos demos containing Modelica (/Coselica) blocks, you need a C compiler, as your message title suggests. Please refer to the compilers page (https://help.scilab.org/docs/6.0.0/en_US/supported_compilers.html) for that. Alternatively, you may try with Scilab 5.5.2 and even report a bug (http://bugzilla.scilab.org) should you encounter unexpected behavior.

When I alter the content of that field, or even pull the scs_m data from Xcos and try to reopen / reload it using the xcos(scs_m) command, all labels inside of superblocks are deleted.

Re: [Scilab-users] Optim use and 'err' flag
To complete my previous answer, the error arose from the built-in line search algorithm (err>10 means different flavors of it failing). In your case, it is pointing to a "too small deltaT", so yes it looks like your algorithm is converging but it has trouble finishing. You can get more info by using "imp=3" in your call to optim (as documented). If you are using a nightly build then use "iprint=3" (the online doc hasn't been updated yet).

Re: [Scilab-users] Xcos - Problem with tf variable name in a superblock
Hi Pierre, What you want to do is check your environment at context evaluation, so simply write a "pause;" at the start of the context and when you press Play you will be prompted to resume in the Scilab console. You can then write "-->who()" or "-->who('get')" to list all existing variables. Note that you can safely overwrite these variables because when you leave your context the modifications will be lost (their scope is limited to the context). Regards, Paul On 2016-06-13 18:44, Perrichon wrote: Hello Paul, Thanks you for your quit response It confirms that « tf » is a reserved word in Xcos context, and must be used with caution. In fact, I shall drive in September a student in Master2 on a subject concerning turbines simulation, and I inherit a program done with Xcos where condition « if ~exists(« foo ») foo=xx » is systematically used, and I see a big number of Xcos blocks and hundreds of variables. This is correctly done because all variables are not necessary transmitted when launching Xcos. Part of them are redefined, part of them are values by default, which explains this program structure done by a student a few year ago. So, has to control that, my main question was to know where I could finf a list of reserved words or variables in xcos.

Re: [Scilab-users] Error during Simulation
Hello Tarun, Could you please attach your diagram file instead of a screenshot of it? The error you are getting is the solver telling you that it could not converge. Indeed, there is a default limit of 500 steps for CVode. The fact that the solver did all of them (delta large enough between two steps) indicates that your system is either going back and forth or slowly converging. It must be one of your CLR blocks that return that error, since they are the only ones in your diagram with continuous states. Changing the solver (Simulation-Setup) or tuning the tolerances may help. Also, what version of Scilab are you using?

Hello, When you type ' plot(X,Y) ', Scilab links together the consecutive [X(i),Y(i)] pairs. In your example, X(40)~6.28 and X(41)=0.

Re: [Scilab-users] Problems with To workspace and From workspace
Hi Michael, When I run the simulation a second time, I still get the "Protected variable name" and "Singularity in a block" (block _expression_) errors. The attached diagram does what I think you are trying to do (without running the script). That is, when the ramp block crosses zero, save the value of the sine block in Scilab environment and plot it. The CLKSOMV_f block is just there to give an initial impulse to DOLLAR_f thanks to the added CLOCK_c block. As Serge stated, the variables are "transferred" to the Scilab environment at the end of the simulation, so there is no way of saving a variable AND loading it mid-simulation in one diagram. Hope this helps, Regards, Paul On 04/14/2014 05:01 PM, Michael Ungelehrt wrote: Hello Paul, thank you for your answer. I had a look at the DOLLAR block.

Re: [Scilab-users] Problem running xcos in batch mode from Scilab
Hello Romain, The difference is due to the solver type. Your diagram currently selects the ODE solver Sundials/CVode - BDF - Newton. xcos_simulate(scs_m, 4); detects two continuous states and switches to a DAE solver (Sundials/IDA). scicos_simulate(scs_m); only detects one continuous state and keeps the ODE solver. This must be due to a Modelica compilation difference between xcos and scicos. I don't know the equations of your model so I cannot assess which method is correct. Also, I noticed that the context variables (C, R, T, end_time) are not present in the diagram, so what are you trying to change when you modify the context? You might want ot use the END http://help.scilab.org/docs/5.4.1/fr_FR/ENDBLK.html block to set the end time.

Re: [Scilab-users] scilab-fortran issues
Hello Eduardo, The call() primitive is not (yet?) suited for string matrices, because there is a confusion about the size of it: right now, the gateway detects the size of a scalar string, but when it is a matrix, each element can have a proper size (buffer) and there is also the matrix size itself. To avoid this confusion, the gateway only allows scalar strings, so the size of the argument actually represents its length (for instance, ident=STR1 will be detected as having a 4x1 size). This is documented in the help page http://help.scilab.org/docs/5.4.1/en_US/call.html, the arguments can be real matrices or [scalar] strings. So my only suggestion at the moment is to pass ident as the concatenation of its elements, and to split it (or iterate on its length) in the Fortran routine. ident = STR1+STR2+STR3+... Hope this helps, otherwise feel free to report a bug on http://bugzilla.scilab.org/ Regards, Paul On 01/15/2014 09:01 PM, Eduardo Torrecillas wrote: Hello all, I am very used to dynamic linking scilab and Fortran, and call the external function by the call function in SciLab.

Re: [Scilab-users] Number of plots limited in Xcos scope?
Hi, Did you try to run your links through a MUX block? The Xcos - Control Systems - Inverted Pendulum demo shows more than 4 plots in one graphic window. Hope this helps, Paul On 10/23/2013 02:56 PM, Florian Würflinger wrote: Hello, im using scilab 5.4.1 and I tried to display more than four plots in one Xcos scope. The first four plots are displayed, all further plots remains emty. Could it be that the numer of plots in a Xcos scope is limited, or is there a bug.

Re: [Scilab-users] Matrix of characters conversion
Dear Paul, How about manually editing your file to standardize the spacing between the numbers? For instance, using your editor's Find and Replace tool to replace two spaceswith one space until you get only one space between each number? Hope this helps, Have a good day, Paul.

Re: [Scilab-users] Solving linear problem in scilab using Karmarkar and Primal Affine Scaling Method
Hello Jennifer, Are you certain that our problems are worrectly written? For intstance, why is there a 2 alone in a line of the first problem ? And why do your right-hand side elements all have x (0x, 1x, 15x)? I cannot rewrite them but I can tell you that yes, karmarkar allows to solve such problems. Just have a look at its help page : http://help.scilab.org/docs/5.4.1/fr_FR/karmarkar.html Your first problem should look something like this: c = [1 -2 0 0 4]'; // Main problem Aeq = [1 0 -1 0 0 ; ? ? ? ? ? ; 1 -2 4 0 -4 ; ? 2 0 1 -4 ; ? 1 1 1 1]; // Equations beq = [0 ? 0 0 1]; // Right-hand side [xopt, fopt, exitflag, iter, yopt] = karmarkar(Aeq, beq, c) If the solution is not all positive (inequality constraint), add an inequality matrix A, like in the help page. Hope that helps, Paul.

Re: [Scilab-users] Xcos error
Hello, This error sometimes occur when you try to move too fast, or when you add blocks successively too rapidly. Try to slow down or empty your diagram before dragging the first block, and let us know how it works. Regards, Paul.
