i need help writing the code for this !

(a) Write MATLAB code to perform the following tasks: 1) Initialize a matrix A to be a 15 15 matrix consisting of all zeros, using the zeros function we have learnt. 2) Using for loop(s), modify A so that the (i, j) entry of the matrix is the sum of the row number and column number (i +j). So, A(1,1) 2, A(2,1)A(1,2) 3, etc. You may need to use more than one nested for loops to accomplish this (b) Assume you are already given a matrix B with n rows in MATLAB. Using for loop(s), write the MATLAB code that returns a matrix C that consists of the rows of B in the opposite order. For example, if then we have Your code should be general and work for any value of n, so you want to start your code by finding out the size of the matrix B. Then switch the order of the rows and assign them to a new matrix C. Make sure to check that your final code works as intended by putting in a specific matrix B and trying it out
