for (i=1:x1)
for(j=1:x2)
Z=zeros(N,M)
end
end
For example if x1=4,x2=4,N=8,M=8 I will have 16 zero matrices(8*8).All are named as z.
I need to name them as z1,z2,z3 ... etc.
Thanks for the help in advance

There are a lot of contributions (one of the best is here) which show why this way of coding is bad - use an efficient way by indexing and take advantage of the methods Matlab gives you:
N = 3;
M = 4;
x1 = 2;
x2 = 2;
Z = zeros(N,M,x1*x2)
gives you a 3D-matrix which has size x1*x2 in the third dimension
Z(:,:,1) =
0 0 0 0
0 0 0 0
0 0 0 0
Z(:,:,2) =
0 0 0 0
0 0 0 0
0 0 0 0
Z(:,:,3) =
0 0 0 0
0 0 0 0
0 0 0 0
Z(:,:,4) =
0 0 0 0
0 0 0 0
0 0 0 0
