Re: Sum of matrices

[Alasdair McAndrew]

I'd use Ben's method, in two steps:

[r,c] = size(B)

sum(reshape(B,c,c,r/c),3)

This only works of course if A is square; so that the number of rows of B is a multiple of the number of columns.

Dear Octavers,

Suppose we have 100 square matrices of order 50: A_1; A_2;...;A_100. We put these matrices in the following manner: B=[A_1;A_2;...;A_50]

how we can write a program performing the sum of these matrices from the matrix B.

Thank you
