With Matlab notation, Use loops to determine the sum of the positive elements of each row in matrix A, and the sum of the negative elements of each row in matrix A (from problem 1).

Problem 1 (10 pts) 10 0 -5 -1 0 1 5 5 0 -1 -1 1 7 7 69 -2 2 3 8 Use loops to create matrix B in which the value of each element is the corresponding value in matrix A divided by the sum of its indices (the row number and column number of the element). For example, value of element (1,1) in B matrix is 10 /(1 1) 5 Problem 2 (10 pts) Use loops to determine the sum of the positive elements of each row in matrix A, and the sum of the negative elements of each row in matrix A (from problem 1)
