MATLAB: Create legend including tex symbols and elements from float array

latexlegend

Hi all

I have an array of floats

eps = [0.1 0.15 0.2 0.25 0.3];

and I would like to use it as input into my legend (replace the hardcoded numbers):

legend({'\epsilon = 0.10','\epsilon = 0.15','\epsilon = 0.20','\epsilon = 0.25','\epsilon = 0.30'},...
  'Interpreter','tex','FontSize',5.5,'Location','NorthEast')

Highly appreciating any ideas! Devin

This works:

epsln = [0.1 0.15 0.2 0.25 0.3];
lgdstr = regexp(sprintf('\\epsilon = %.2f\n', epsln), '\n', 'split');
legend(lgdstr(1:end-1), 'Interpreter','tex','FontSize',5.5,'Location','NorthEast')

MATLAB: Fourier analysis of waveforms and clipping wave, HELP PLEASE!!!

I'm not sure how you are using the term "period" here. If you are talking about only the first 1 of the fundamental frequency which is 1 MHz here, then I think you want at least a few periods to do a spectral analysis even with a clean waveform. The resolution in the DFT (implemented by fft) depends on the number of samples. The more samples, the better the resolution.

In your case, it's easy to see that

xnew = x(1:2800);

gives you the initial waveform, so why not use this?

     Fs = 1/1e-8;
     d = fdesign.lowpass('Fp,Fst,Ap,Ast',1.2e6,1.4e6,0.5,60,Fs);
     Hd = design(d,'butter');
     xnew = x(1:2800);
     y = filter(Hd,detrend(xnew,0));
     ydft = fft(y);
     freq = 0:Fs/length(y):Fs/2;
     ydft = ydft(1:floor(length(y)/2)+1);
     % Plot in MHz
     plot(freq./1e6,abs(ydft))
     axis([0 10 0 max(abs(ydft))+20])
     xlabel('MHz'); ylabel('Magnitude');

If you copy and paste the above code, it works fine.
