Function AXL
Function AXL converts an array (matrix) into a list, and vice versa. For
examples,
Note: the latter operation is similar to that of the program CRMR presented in
Chapter 10.
Function AXM
Function AXM converts an array containing integer or fraction elements into its
corresponding decimal, or approximate, form. For example,
Function LCXM
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
ij
=
(i+j)
2
, first, store the following program into variable P1 in RPN mode. This is
the way that the RPN stack looks before pressing
K.
