Given the following MATLAB code, convert the nested for loops to nested while loops. Make sure the two coding examples produce the same results, in content and format. A = [7, 5; 3, 9; 1, 2); row = 3; % it's best to use variables instead =2; % of fixed numbers sum = 0; for (i = 1:row) % loop over rows for (j = 1:col) % loop over columns sum = sum + A(i, j); end sum Create a coding sequence that will accept as prompted input, one field -month Name, this is a string value. Now create a branching set of code, using else if clauses, which will assign the number of days in the month. Use the following information to establish the month day relationship: Feb: 28 Apr, Jun, Sep, Nov: 30 Jan, Mar, May, Jul, Aug, Oct, Dec: 31 the output stream should look like: "Jan has 31 days". Use either dips or f print f function to generate the output
