I want to use fft on first cycle of sine wave to get all samples from it.
fs=1000; t = 0:1/fs:0.2-1/fs; x = 5*sin(2*pi*50*t); plot(t,x)
To do it I used loop:
n = 20; for i=n:length(x) y = fft(x(i:i+n-1)); end
where n is number of samples/cycle (fs=1000, freq=50 Hz).
But MATLAB shows me an error "Index exceeds matrix dimensions" in line with y = fft(...).
How to fix it?
Artur Pater This means that you have specified an index value greater than the limit of its dimensions assigned by the array. For example, a for statement doing 10 loops and you assigned an index value of 101 while its maximum array dimension is 100, this will give you an "index exceeds array dimensions" error. In the reference below is the answer to your question, check out:
