Matrices

This chapter is an introduction to the matrix data type. Matrices are the most commonly used data type in   and there are many powerful operations and functions you can perform on them. A matrix is generally a two dimensional array of scalars, although also supports string matrices, see Chapter [*]. All numeric operations and functions work for any combination of real and complex operands or arguments. The elements inside a matrix are refered to by the number of the row and column they are in. Rows are specified first and go across, and are numbered from top to bottom. Columns go down, and are numbered from left to right.
