MATLAB Problem:

In linear algebra, if T is a square matrix and v is a column vector, and the following conditions holds: Tv = lambda v, then v is an eigenvector of T, and scalar lambda is the corresponding eigenvalue. Write a function iseigen that will receive a 3 times 3 matrix T and a 3 times 1 vector v of real numbers. It will return a logical true if v is an eigen vector of T, otherwise it will return a logical false. If the function call expects two output arguments, the function will also return the corresponding eigenvalue provided that v is an eigen vector of T, otherwise it will return NaN as the second output
