Write a user-defined MATLAB function that calculates the determinant of a 3 Ã— 3 matrix by using the formula:

For the function name and arguments, use d3 = det3by3 (A), where the input argument A is the matrix and the output argument d3 is the value of the determinant. Write the code of det3by3 such that it has a subfunction that calculates the 2 Ã— 2 determinant. Use det3by3 for calculating the determinants of:
(a)
