How to subtract corresponding elemets of corresponding columns of two matrices?

1 次查看(过去 30 天)
Hi,
I have two matrices, say a = [P1 P2 P3], while size of each (P1, P2, P3) is i.e size(P1) = 100 1, etc.
similarly other matrix b = [Q1 Q2 Q3], while size of each (Q1, Q2, Q3) is i.e size(Q1) = 100 1, etc.
I want to differentiate a - b in such a way that each element of fisrt column P1 is being subtracted from corresponding elemt of Q1 and similarly
each column of fisrt column P2 is being subtracted from corresponding elemt of Q2 and so on....
How can I write its code?

"each column of fisrt column P1 is being subtracted from corresponding elemt of Q1". That's a confusion. You meant rows, right? If you want to subtract matrix a and b, then why not just do
a - b;
