I want to write a function EIGENSPACE, which takes a matrix A and a scalar k as argument and returns a matrix which columns form the eigenspace k of A.

A = [0,0,4;1,0,-17;0,1,8]

I guess I first have to write a function for row reductions and then identify the null-space from the (R)REF of A-k*eye(size(A)) OR something like this:

null(A-k*eye(size(A)), 'r')

Thanks in advance
