How could i save the data of this matrix in diffrent mat files with the names:

Use a for loop, create the filenames, index into the array and save.
Why do you want them all in different files though? For a lot of usages they would be better kept together and indexed into.

something like this:
A(4, 4, 5)=1;
[~, N, M]=size(A);
for ii=1:N
for jj=1:M
Charii=num2str(ii);
Charjj=num2str(jj);
Var=A(:, ii, jj);
FileName=['''Data' Charii '_' Charjj '.mat'''];
VarName=['''Var'''];
eval(['save(' FileName ',' VarName ')'])
end
end
