MAD and RSD are related to the solution of systems of linear equations and will
be presented in a subsequent section in this Chapter. In this section we'll
discuss only functions AXL and AXM.
Function AXL converts an array (matrix) into a list, and vice versa:
Note: the latter operation is similar to that of the program CRMR presented in
Function AXM converts an array containing integer or fraction elements into its
corresponding decimal, or approximate, form:
Function LCXM can be used to generate matrices such that the element aij is a
function of i and j. The input to this function consists of two integers, n and m,
representing the number of rows and columns of the matrix to be generated,
and a program that takes i and j as input. The numbers n, m, and the program
occupy stack levels 3, 2, and 1, respectively. Function LCXM is accessible
through the command catalog ‚N.
For example, to generate a 2´ 3 matrix whose elements are given by a
first, store the following program into variable P1 in RPN mode. This is the way
that the RPN stack looks before pressing K.
