comp.soft-sys.matlab - The MathWorks calculation and visualization package.
I have installed matlab 7 (R14) on my machine running windows 2000. After installation everything worked fine. However, after I restarted the machine, the plot command does not bring up the plots. I am not getting any error messages on the command line (I know that the data is good). The demos are not working either. Basically, anything that pops up a gui or a new window does not work. MATLAB itself is running fine, my codes run fine. The plots are simply not showing up. I have tried updating/reinstalling JVM and uninstalling/reinstalling matlab itself. Does anyone know why this is happening? Is there a fix for this? -thanks sri
Gd day everyone, I have a few questions which need some clarifications desperately. Currently i have used a specgram command in matlab to do a short time fourier transform or STFT on a signal. my command goes like: nfft = 512; Fs = Fsnew; window = 51; num_overlaps = 1; [C1,F1,T1] = specgram(signal, nfft, Fs, window, num_overlaps); % Computes the STFT of x Matlab returns me a -F1 array of 257 by 1 -T1 array of 527 by 1 -and a C1 array of 257 by 527 Is there a way to make my F1 and T1 of the same size? I then did a coherence estimate by adding up the sum of the cross terms, and taking its absolute value, and square all that, then divide it by the sum of the auto terms at each Frequency values. Therefore i had a coherence matrix of 257 by 1. I wanted to do a mesh plot of T1,F1 and coherence but because coherence is a vector. The mesh plot wont execute. Is there anyway to execute a mesh plot of the variables with the above array sizes mentioned above? Pls give me some feedback, i will be very much grateful. Thanks.
