HELP how to solve this error code : Error using .* Matrix dimensions must agree.

Hi, Well in fact I have a problem with my code which is generating the error below, could you help me to solve this please, here's a part of the code :

[val_maxfft(icurv,:),loc_maxfft(icurv,:)]=(max(Y0fft(:,1,icurv)));

freqY0=(1:Ndf)*df;

PhiY0_decal=-2*pi*(freqY0')*(loc_maxfft(icurv,:)-1);

PhaseY0_shift=complex(cos(PhiY0_decal),sin(PhiY0_decal));

Arg_Phase_shift=atan(imag(PhaseY0_shift)./real(PhaseY0_shift))

Y0fft=Y0fft.*PhaseY0_shift;

Y0_BP=Y0fft(loc_maxfft(icurv,:):loc_maxfft(icurv,:)+Ndfmax-1,1,1);

The error is generated for this line: Y0fft=Y0fft.*PhaseY0_shift;

And thank you for your help

What are the results of:

   size(Y0fft) 
   size(PhaseY0_shift)

They need to be the same size and shape to use the .* operator.

Here's the result :

 size(Y0fft)

ans =

       42823           1           2

>> size(PhaseY0_shift)

ans =

       42823           1

I know that they have the same size, but I don't know how to do it, i''m a little confused.

I know that they should* have the same size, but I don't know how to do it, i''m a little confused.

Sorry for the mistake.
