u Creating a Matrix

To create a matrix, you must first define its dimensions (size) in the Matrix Editor. Then you can input values into the matrix.

u To specify the dimensions (size) of a matrix

Example To create a 2-row ⋅ 3-column matrix in the area named Mat B

Highlight Mat B.

c

cw

Specify the number of columns.

dw

w

• All of the cells of a new matrix contain the value 0.

#If “Memory ERROR” remains next to the matrix area name after you input the dimensions, it

means there is not enough free memory to create the matrix you want.
