Find sum of individual matrix of a given array of matrices and store it in a temporary array

Suppose M[l,m,n] an array of m*n matrices of size l, and then required to find sum of individual matix and store it in a temporary array .

eg: l=2 m=3 n=3

M[1,m,n]={{0,1,1},{0,0,0},{1,1,1}}=sum(M[1,m,n])=5

M[2,m,n]={{0,1,1},{0,1,0},{1,1,1}}=sum(M[2,m,n])=6

Finally,

store final sum values of each matrix in to a temporary array.

temp[1,l]={5,6}

That is,

temp[1,1]=5

temp[1,2]=6

Being M your matrix:

sol = sum(sum(M,3),2)

works as expected,
