My Pleasure. See attachment. I think you need the full datafile as I have done windowing before saving it.<br>Regards,<br>Sumit<br><br><br><div class="gmail_quote">On Tue, Sep 15, 2009 at 5:10 PM, Yann Collette <span dir="ltr"><<a href="mailto:yann.collette@scilab.org">yann.collette@scilab.org</a>></span> wrote:<br>

This is happening for only one data file!!!. Other dumps of the same tracepoints are working. I cant attach the core. It is 1.8 GB!<br>
Same file with 4.2.1 working fine.<br>
<br>
Following is the script :<br>
<br>
// Clearing the previous data (if any)<br>
clear all ;<br>
<br>
// Handling stacksize<br>
stacksize('max');<br>
<br>
<br>
function fft_plot()<br>
<br>
// Sampling Frequency Specification :<br>
Fs = 1024.0*1024.0;<br>
<br>
// Sampling Time Period Specification<br>
delt = 1.0/Fs;<br>
<br>
// Data File Read Up :<br>
printf(" MESG :: Reading Data File ...... \n");<br>
file_read_out = fscanfMat("./data.dat");<br>
<br>
<br>
// Expansion of Time :<br>
t = 0.0:1.0/Fs:(size(file_read_out,"*")*delt);<br>
<br>
// Finding Out Number of Samples :<br>
N = size(t,'*');<br>
<br>
// Clearing the array t<br>
clear t ;<br>
// Computing FFT :<br>
printf(" MESG :: Computing FFT ...... \n");<br>
fft_out=fft(file_read_out);<br>
<br>
// Clearing the array file_read_out<br>
clear file_read_out ;<br>
<br>
// Expanding Frequency :<br>
f = Fs*(0:(N/2))/N;<br>
n = size(f,'*');<br>
<br>
// Setting Plot Down Sampler :<br>
RDOWN = 1 ;<br>
<br>
// FFT Graphical Plot :<br>
printf(" MESG :: Plotting FFT .... \n");<br>
plot(f(1:n/RDOWN),20*log10(abs(fft_out(1:n/RDOWN))),"red"); mtlb_grid("on");<br>
//plot(log10(f(2:n/RDOWN)),20*log10(abs(fft_out(2:n/RDOWN))),"red"); mtlb_grid("on");<br>
//plot(f(1:n/RDOWN),abs(fft_out(1:n/RDOWN)),"red"); mtlb_grid("on");<br>
xtitle( 'FFT Plot of Output Signal', ' Frequency (Hz) ', 'Gain (dB)') ;<br>
<br>
endfunction<br>
