How to solve matrices problem

Hi, I have few questions: 1. Let say I have a = [1 2 3; 4 5 6; 7 8 10] and I wanted to have 10 times of matrix a? How to do that? 2. I have 10 different matrix with the same size,for eg. 3x3, how to add all these 10 different matrix?

Try this for #1:

a = [1 2 3; 4 5 6; 7 8 10]
aWide = repmat(a, [1, 10]) % Create 3 by 30 matrix.
aTall = repmat(a, [10, 1]) % Create 30 by 3 matrix.

Try this for #2:

aAll = a1 + a2 + a3 + a4 + a5 + a6 + a7 + a8 + a9 + a10;
