Question: For a general matrix A, write a python code to find A inverse by first applying LU decomposition on A and then solving the n

For a general matrix A, write a python code to find A inverse by first applying LU decomposition on A and then solving the n linear systems LUxi = ei for 1 <= i <= n with appropriate substitution methods. Here ei is the standard basis vector with a 1 in the i-th entry and 0 everywhere else.
