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 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?
