## General Matrices, real matrices, complex matrices, integer matrices.

"... a matrix is an array of numbers ..." I have a (somewhat pedantic) objection to this. Partitioned matrices are often dealt with as an array of matrices, not an array of numbers. And matrices over other domains (logic values) exist in the literature. [Admittedly these can, like anything, be represented as numbers.)

Perhaps something like "... a matrix is an array of elements which are usually numbers"? with a followup line something like "A matrix with real elements is called a 'real matrix', one with complex elements is called a 'complex matrix', etc."

Or is the feeling in the community that basic matrix page is too early to make such distinctions? John Halleck 11:02, 8 November 2007 (CST)

If I hear no objections, I'll just make the changes. John Halleck 12:39, 9 November 2007 (CST)

## Reorganize?

The current organization with "inverse" being a special type of matrix, instead of a type of matrix operation makes it difficult (for me) to make the comments in the article more general. Unless I hear otherwise I'm planning to do some major reorganization. John Halleck 19:51, 14 November 2007 (CST)

## Title

This aticle will probably need to be moved to Matrix (mathematics) or something similar one day to make way for disambiguation: there are other scientific uses of the word "matrix". Richard Pinch 06:53, 10 December 2008 (UTC)
