Publish using a MatLab function for the following:
If a matrix A has dimension n×n and has n linearly independent
eigenvectors, it is diagonalizable.This means there exists a matrix
P such that P^(−1)AP=D, where D is a diagonal matrix whose diagonal
entries are made up of the eigenvalues of A. P is constructed by
taking the eigenvectors of A and using them as the columns of P.
