Try something like this —

A = rand(7,5)

A = 7×5

0.5913 0.0197 0.5496 0.4826 0.8172 0.0226 0.2084 0.4920 0.3916 0.4963 0.3309 0.6599 0.3613 0.7490 0.0767 0.8878 0.2860 0.8968 0.3605 0.1475 0.8661 0.5546 0.8458 0.8396 0.9193 0.8801 0.9111 0.8651 0.2889 0.7545 0.2091 0.5319 0.4838 0.8030 0.0023

Anew = A(:,1:end-2)

Anew = 7×3

0.5913 0.0197 0.5496 0.0226 0.2084 0.4920 0.3309 0.6599 0.3613 0.8878 0.2860 0.8968 0.8661 0.5546 0.8458 0.8801 0.9111 0.8651 0.2091 0.5319 0.4838
