Thanks for the suggestions.

My only point in the original post was with one-dimensional initializers having that little bug. I understand there are many work-arounds.

And my comment about "intended for algebra" was really about how the Matrix procedure was written with that particular type check, not about what one could do with them.

Thanks again for all the replies.

Thanks! That greatly clarifies the issue.

i guess a Matrix is only intended for algebra.
