Matrix Data Input Format
[OPTN] - [MAT/VCT] - [Mat]
The following shows the format you should use when inputting data to create a matrix using
the Mat command.

• The maximum value of both
m
and
n
is 999.
• An error occurs if memory becomes full as you are inputting data.
• You can also use the above format inside a program that inputs matrix data.
