Please comment the MIPS code to help me understand.

Here is what the code accomplishes.

Here is the code, partially commented.

Background A square matrix A is symmetric if where AT is the transpose of the matrix A. That is, a for all values of indices i and j (where aij represents entries in A). For example, matrix A below is symmetric but B is not. 1 17 23 B-5 2 7 A- 5 2 7 Project Objective Our objective in this project is to check if a given Matrix is symmetric or not. We perform this with the following two steps. . Given a square Matrix, we first compare if aj aji for all entries. If they are equal we write "O" for those entries. If not we write "1". So if all the elements of a Matrix are "O" then it is a symmetric matrix. Note that the diagonal would always end up as "O". We write back to the same matrix location. E.g.: For the above Matrices A and B the final result would be A- 0 0 0 B- 1 0 0 We also aim at measuring the asymmetry. So we will be counting the number of entries in a matrix which are not equal to its mirror entry. Basically define a counter and increment the counter by 1 if aj # aji. For the above Matrix B, the value of counter would 2 as two elements are different
