Suppose I need to estimate a parameter matrix and one way is to write the derivation in matrix form and get the optimized matrix directly, the other way is the estimate each row of the matrix and then form the optimized matrix. I found these two methods didn't give the same results. what would be the possible reason?

What's the difference between two way to estimate a parameter matrix?
