Matrices - what is a matrix
... This leaflet will explain what is meant by a matrix and the notation we use to describe matrices. We will also look at some special types of matrix. A matrix is a rectangular pattern of numbers - we usually enclose the numbers with brackets. So, for example, the following are all matrices. ...

... (R1) All zero rows appear below nonzero rows when both types are present in the matrix. (R2) The first nonzero element in any nonzero row is unity. (R3) All elements directly below (that is, in the same column but in succeeding rows from) the first nonzero element of a nonzero row are zero. (R4) The ...
