MATLAB: Select complex numbers from cell array based on the real part

Question

Hi all,

I have a 7D cell array with complex numbers.

I want to keep the complex number with the highest real part, of all the values of the 3rd parameter (1:15).

For example in this case i want only the val(:,:,14,1,1,1,1) which has the highest real part.

I tried to do it using the following command

maxVal = max(cell2mat(my_array),[],3);

However, it keeps the complex number with higher imaginary part. In this case

val(:,:,15,1,1,1,1)

Any idea of how can i do this?

Thank you

Well, if you want the max() of the real part, then you'll have to limit to only looking at the real part -- max() for complex returns max(abs())

tmp=squeeze(cell2mat(my_array));
[maxRealVal,imxR] = max(real(tmp));
maxVal=tmp(imxR);
