Hi I am trying to run the fft command on my matlab waveform that I generated.
I created a superimposed waveform of to generate harmonics. The fundamental frequency is 60 Hz and the high frequency is 900 Hz. I want to be able to show each of the harmonics in the FFT spectrum

Subscripted assignment dimension mismatch.
I am only trying to assign A to the cell with row 1 and...
Hi,
I am a newbie in matlab. I am trying to initialize an empty matrix with certain dimensions.

tabuList = [X,Y];
for i = 1:5
tabuList(i,1) = 'EMPTY';
end
However, I get the following error
