Create a function to solve the system AX = B, for A, X, and B, n x n matrices. The function should take as input matrices A and B and give the output X. Validate your code. Explain how you validated and provide any relevant output. Note: This only requires a slight modification to the code you created in Problem Set 3, Number 3b. Create a function to compute the inverse of a square n x n matrix A. The function should take as input the matrix A and give the output A-1. Validate your code. Explain how you validated and provide any relevant output.
