u Matrix Data Input Format
The following shows the format you should use when inputting data to create a matrix using
the Mat command.

→ Mat [letter A through Z]
Example To input the following data as Matrix A:
!+( [ ) !+( [ ) b,d,f
!-( ] ) !+( [ ) c,e,g
!-( ] ) !-( ] ) aK2(MAT/VCT)
1(Mat) av(A)
w
• The maximum value of both
• 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.
u To input an identity matrix
Use the Identity command to create an identity matrix.
To create a 3 × 3 identity matrix as Matrix A
