Converted matrix has less elements than original one. How do you want to remove these extra elements? I think an example would help.

Hey Mohammad,
Going by those input and output dimensions, I am assuming that you want to extract a part of the matrix with a given value in dimension 1.
If you want to get ith value from dimension 1, use:
crop = mat(i,:,:,:);
to get 'crop' of size [1 512 512 150].
Then use the squeeze function to remove all dimensions of size 1.
crop = squeeze(crop); %this makes size = [512 512 150]
Have a look at the doc for squeeze
Cheers!
