Hey guys. Can anyone help me convert the 'princomp' command to 'pca' ? Below are the coding.
pca_coeff{i} = princomp(feat');
pca_coeff{i} = pca_coeff{i}(:, 1:floor(size(feat,1)/2))';
In the MATLAB, it says that 'princomp has been removed. Use pca instead.'
Thank you. I'm very appreciate if there any answer from anyone.

Hey @Mohamad Afiq
The “pca” function is a replacement for the “princomp” function that works in recent releases.
Replace the first line from
pca_coeff{i} = princomp(feat');
to
pca_coeff{i} = pca(feat');
I hope this helps!
