[Scilab-users] gateway compatibility
Dear all, I noticed that the gateway routines are not binary compatible between 6.0 alpha and 6.0 beta. Also the source has changed somewhat, so the ilib_gen_gateway has to be rerun to update source (particularly C_GATEWAY_PROTOTYPE changed to STACK_GATEWAY_PROTOTYPE) Will the 6.0 beta gateway routines be binary compatible with the 6.0 release? Many thanks, best wishes, Jasper. ___ users mailing list users@lists.scilab.org http://lists.scilab.org/mailman/listinfo/users

[Scilab-users] Maximum allocation with Scilab 6.0 beta
Hi all, For testing purposes, I am trying to allocate big chunks of memory with scilab 6.0beta. I have ~256GB of free ram on my machine, however, Scilab fails creating variables that are way smaller than that: --> a=rand(10,10); Can not allocate 8.00 MB memory. Any idea what is going on? What is the actual ram limitation with the new "stackless" scilab? Cheers, Antoine ___ users mailing list users@lists.scilab.org http://lists.scilab.org/mailman/listinfo/users

Hello,
I'd like to use \b, for backspace as in C, in mprintf function but it
seems to not be implemented. How it can be obtained? (Only \n, \r and
\t seems to be implemented.)
.
with ascii(8) ?
.
apparently not (Scilab 5.5.2 and 6.0-b1):
--> "abc"+ascii(8)+"def"
ans =
abcdef
--> mprintf("abc"+ascii(8)+"def")
abcdef

Ok, because it is not clear whether this bug is related to another one I
decided to enter a new bug report:

I appreciate your help; however, neither suggestion works: I still
get the same error message.
The similar line
[frq,repf]=repfreq(hz,0.01,0.49);
has no problem
You are right the problem is exactly for the frequency 0.5 besause
exp(2*%pi*%i*0.5) -> - 1. + 1.225D-16i
and hz.num has 2 zeros very near -1
I checked the hz value with Matlab, the results are the same. So it
seems that hz is ok. So it is probabily a probleme due to floating point
computations procucing a zero value instead of a very small one.
Serge
please can you save the hz value using the Scilab save function and
send the file?
Serge
Voila le code:
//filtre Butterworth
Order = 2; // The order of the filter
Fs = 1000; // The sampling frequency
Fcutoff = 40; // The cutoff frequency
// We design a low pass Butterworth filter
hz = iir(Order,'lp','butt',Fcutoff/Fs/2,[0.1 0.1]);
// We compute the frequency response of the filter
[frq,repf]=repfreq(hz,0,0.5);
[db_repf, phi_repf] = dbphi(repf);
// And plot the bode like representation of the digital filter
subplot(2,1,1);
plot2d(Fs*frq,db_repf);
xtitle('Obtained Frequency Response (Magnitude)');
subplot(2,1,2);
plot2d(Fs*frq,phi_repf);
xtitle('Obtained Frequency Response (Phase in degree)');
iir est sauvegardé dans "svgd_iir" joint (binaire).
