Algebraically substituting in a matrix requires more than the subs function.

Substitution of a value in a matrix can be done by:

One can combine this with the seq command to create a whole list of matrices.

Note that the eigenvalues and eigenvectors of a matrix can be computed by

For complex eigenvalues, the matrix w2 contains the real part of the eigenvector in one column, and the imaginary in the next

Hence one can form a matrix of actual eigenvectors by:
