Hi, i have 2 enormous matrices A and B which are parameter relevant. With find() function i know which elements are non zero and with find(A-B) i know which elements are changed due to parameter. But how can i find out the indices of elements which remain constant?

Exactly how big are your arrays? Hundreds of millions of elements or more?

Do you mean the non-zero elements that are the same between the two arrays?
A = [1 2 0; 0 1 0; 5 0 8];
B = [1 3 0; 0 4 0; 5 0 6];
[r,c] = find(A==B & A~=0)
