Hey,

I wanted to calculate the eigenvalues and vectors of the following matrix:

A:=Matrix(6, 6, {(1, 2) = k_noho2*NO, (2, 2) = -k_noho2*NO, (2, 5) = k_ipro*O2, (2, 6) = k_hypro*O2, (3, 3) = -k_ro2no*NO, (4, 4) = -k_ro2no*NO, (5, 3) = .991*k_ro2no*NO, (5, 5) = -k_ipro*O2, (6, 4) = .977*k_ro2no*NO, (6, 6) = -k_hypro*O2}, datatype = anything, storage = rectangular, order = Fortran_order, shape = [])

There are no problems with calculating the eigenvalues, but when trying for Eigenvectors(A) it's telling me

Error, (in LinearAlgebra:-Eigenvectors) cannot determine if this expression is true or false: 0 < k_noho2*NO

So what's the problem here?
