take care that i.*.ones(j) generates a vector of size 130321^2 which is
near 2^34. With the current Scilab, the array dimensions (ans pointers)
are stored in 32 bits integers. The crash is probably due to a missing
test on dimensions in the kronecker product gateway.
Butindependently of that
For safe mode you can use tlist with no field names. See the example in the

First, is there a way to get it to stop? ctrl-C does not do the job.
In your startup file
I think
save('testall.data','all')
does the job

Can scilab5.5.2 save all variables without writing the names of all
variables?
The following script failed at the last line.
scilab6.0 alpha can save all variables.
x=1:10;
y=10;20;
in zeta you will give the locations (relative to y) of your boundary
conditions
in your case something like [0 0 0 , L L L ]
if you have 6 states 3 with initial constraints and 3 with final contraints
The constraints should then be defined by the gsub and dgsub functions

Try with lower solver tolerances with the Simulate/Confiure menu.

It is possible to achieve what you want using the following instruction.
It is a little tricky, may be a C format expert can do it in a more
simple way.
u=mopen("",'r')
x=mfscanf(-1,u,"%*s %*2s%*[:]%*2s%*[:]%*2s%*[;]%g%*s");
mclose(u)

Thers is no stair function but you can obtain this king of plot using
the polyline_properties:
clf;plot(sin(linspace(0,2*%pi,40)))
e=gce();//plot creates an entity of type compound
p=e.children;//the handle on the polyline
p.polyline_style=2; //set stair case mode

Hello,
How to change subplot size of figure but not to change the whole size
figure? I have managed to change one subplot size but I also changed the
whole figure to that size.
Thanks, Petar

Here is an example
//First draw the "champ". System1 does not depend on time so the time value is
not used
xr=130:10:290;yr=5:0.3:9;t=0;
clf();fchamp(System1, t, xr, yr)
//now draw the trajectory from given initial point
t=0:0.1:30; //It is not useful to ask for too many points,

The style argument rule the color of the lines and it appear to work as
expected under sclab-5.5.2 (Linux) voir fichier joint.

Hi Rafael,
Thank you very kindly for your assistance so far!
If I understand correctly, the unwrap() macro quoted in your message has
been part of Scilab since somewhere in 2014, am I wrong?
Using scilab's phasemag() macro as suggested, I get the
You can create a scilab.ini file the directory pointed to by the Scilab

The plot instruction should be inside de loop

for Te = 5000:1:25000 // start: step: end
k=k+1
D = E*Te .^3/(12*(1-v^2));
lamda = ((rho_m-rho_fill)*g ./(4*D)).^0.25;

Hi Serge,
I am working with grid data, so looking for the 2D Hilbert, the
results I think should appear similar to doing a directional
derivative, where X highlights features with N-S trends and E-W for Y.

Hello
A quick query. How would one define the Hilbert transform of a grid
for X and Y directions; looking for two solutions Hx and Hy (for the
real values).
Can you explain more precisely what you expect?
Do you want to apply Hilbert transform to
May be you can use optim instead of fsolve using f(x)^2+alpha*norm(x)^2
as cost function with alpha small enough
If you cannot compute the gradient of the cost function you can use the
numderivative function to estimate it.
