MATLAB: Define a Sparse Matrix without sparse function.

Question

Hello I wonder if it is possible to define a sparse matrix without using the sparse function, is that I simply put the values in the position I want.

Thanks.

The sparse command can use multiple input formats:

E.g.,

"S = sparse(i,j,s) uses m = max(i) and n = max(j) ... Uses vectors i, j, and s to generate an m-by-n sparse matrix such that S(i(k),j(k)) = s(k)"
