To use the program in ALG mode, press @CRMC followed by a set of parentheses
( „Ü). Within the parentheses type the lists of data representing the
columns of the matrix, separated by commas, and finally, a comma, and the
number of columns. The command should look like this:
CRMC({1,2,3,4}, {1,4,9,16}, {1,8,27,64}, 3)
The ALG screen showing the execution of program CRMC is shown below:
Lists represent rows of the matrix
The previous program can be easily modified to create a matrix when the
input lists will become the rows of the resulting matrix. The only change to be
performed is to change COL
→ for ROW → in the program listing. To perform
this change use:
‚@CRMC
List program CRMC in stack
˜‚˜—ššš Move to end of program
ƒƒƒ
Delete COL
~~row~` Type in ROW, enter program
To store the program use: ³~~crmr~ K
{1,2,3,4} ` {1,4,9,16} ` {1,8,27,64} ` 3 ` @CRMR
The following screen shots show the RPN stack before and after running
program
@CRMR:
These programs can be useful for statistical applications, specifically to create
the statistical matrix
ΣDAT. Examples of the use of these program are shown
in a latter chapters.
