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."
