Dennis,
This works well and is exactly what I wanted for these matrices. Thank you
very much, however, when I would try to export the resulting list it just
is bound by columns. Now this isn't so bad for 2 matrices but I hope to
apply this where there are many matrices and scrolling down a file such as
a 'csv' would be desired. Any thoughts on exporting a list of matrices?
Thanks,
Charles
