eigenvalues, part: fell off the end



To print the matrix in a form that is easier to copy and paste, set display2d to false; for example

(%i6) display2d : false$
(%i7) matrix([1,3],[3,5]);
(%o7) matrix([1,3],[3,5])

I'd also suggest that you not apply float to the matrix--post it to this list without using float.

It so happens there already is an active ticket
for the 'unsolvable eigenvalues 10x10', #2183
(issued by you, I think).

And I don't know Maxima well enough yet to
produce an input from matrix I fill in my
program. The result of print(float(opH)) with
empty lines removed is:
