create a Matlab code that uses random matrices of random sizes (In this part, m and n are both integers and both are greater than 6, so 7 or larger) and find empirical evidence to show proof of the following statements using the code you have written.

(a) Typically, a set of n linear equations with n unknowns has a unique solution.

(b) Typically, a system of m linear equations in n unknowns, where m > n, does not have a solution.

(c) Typically, a system of m linear equations in n unknowns, where m < n, has numerous solutions.

Additionally, provide examples of exceptions for each of these cases (using integers m and n that are greater than 2).
