MATLAB: FFT in 3D matrix

Question

Hi all,

is there any pssibility wothout for loop to do the FFt of this:

F_domain = FFT (t_domain). t_domain is a matrix of 3D (800*10*200). the time axis is the First dimension (800). the second dimension is repetition of the Measurement. the Third dimens is the number of measurements.

Thank you all

Answer 1

I'm not quite sure what the second and third dimensions are, but assuming you want each column transformed on the time dimension, you would do this:

F_domain = fft(t_domain, [], 1);
