data_mat=load('filename.mat');
fft_result=fft(data_mat)
Please carefully check the size and details of the loaded mat file.
See the Matlab Doc FFT function here
Plot, hope you can do that
If variable are 1 D
Use plot()
2D Variable See the surf function
There are multiple ways of data visualization (plot function), check the dimentions of the plot variables and plot accordingly as per your requirement.
