MATRIX ADD ROW
Name:
Type:
Purpose:
Add a row to an existing matrix.
Description:
It is sometimes convenient to add an observaton (i.e., a
row) to an already existing data matrix. This command
allows you to do that in a simple way.
Syntax:
LET <mat2> = MATRIX ADD ROW <mat1> <x>
where <mat1> is the original data matrix;
<x> is a vector containing the data values for
the new row of data;
and where <mat2> is the resulting matrix.
Note that <mat2> is typically the same as <mat1>.
Also, the number of rows in <x> should be equal to the
number of columns in <mat1>.
Examples:
LET M = MATRIX ADD ROW M X
Note:
Matrices are created with either the READ MATRIX command or the
MATRIX DEFINITION command. Enter HELP MATRIX DEFINITION and HELP
READ MATRIX for details.
