u 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.
= [ [a
11
, a
12
, ..., a
1
n
] [a
21
, a
22
, ..., a
2
n
] .... [a
m
1
, a
m
2
, ..., a
mn
] ]
→ 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 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.
u To input an identity matrix [OPTN] - [MAT/VCT] - [Identity]
Use the Identity command to create an identity matrix.
Example To create a 3 × 3 identity matrix as Matrix A
K2(MAT/VCT) 6( g) 1(Identity)
da6( g) 1(Mat) av(A) w
