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 statistical matrix ΣDAT. Examples of the use of these program are shown in
a latter chapters.
