Hey guys thanks in advance for reading this and helping me.

I have a matrix range_compression(2032 x 400). For each column of that matrix I want to apply a function(freq2time).This function transforms a vector in frequency domain to a vector in time domain.

I want that after the apllication of the function for each column of range_compression, it saves the variable range_compressed, column by column in another matrix. And for each time_compression variable, multiply by speed of light and save in another matrix.

How can I do this, thank you. This is the code I have, but im having difficulties on doing the rest

[nr,mr]=size(Range_compression);
for i=1:mr
    [time_compression,range_compressed]=freq2time(mr,doppler_freqSurv);

在 MATLAB Online 中打开

[nr,mr]=size(Range_compression);
 [time_compression,range_compressed]=deal(nan(nr,mr));
for i=1:mr
    [time_compression(:,i),range_compressed(:,i)]=freq2time(mr,doppler_freqSurv);
end
time_compression=time_compression*speed_of_light;
