deleting rows from matrix and saving as a new matrix

Hello,

If I have a matrix 20 x 20, and I want to delete row 2 and 7,

I would use something like

MTX_1([2,7],:) = []

is there a way to save this new matrix as a separate array (such as MTX_2), while preserving the original MTX_1?

Thank you.

Probably the easiest way:

MTX_2 = MTX_1(setdiff(1:size(MTX_1,1),[2,7]),:)

This creates ‘MTX_2’ while leaving ‘MTX_1’ unchanged.
