Re: Large Matrix Multiplication

[Robin Kramer]

I upgraded to GNU Octave 2.1.50, and the error went away.
for completeness.

On Octave 2.1.42 the line

eye(80)*eye(80);  was causing an error

panic: illegal instruction -- stopping myself
Signal 4

This was not the case for lines such as

eye(80)+eye(80);

or even

eye(160)+eye(160);

Thanks for the help.
