Example To input the following data as Matrix A:
!+( [ ) !+( [ ) b,d,f
!-( ] ) !+( [ ) c,e,g
!-( ] ) !-( ] ) aK2(MAT)
1(Mat) av(A)
w Matrix name
• 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] - [Iden]
Use the Identity command to create an identity matrix.
Example To create a 3 × 3 identity matrix as Matrix A
K2(MAT) 6( g) 1(Iden)
da6( g) 1(Mat) av(A) w
Number of rows/columns
u To check the dimensions of a matrix [OPTN] - [MAT] - [Dim]
Use the Dim command to check the dimensions of an existing matrix.
Example 1 To check the dimensions of Matrix A
K2(MAT) 6( g) 2(Dim)
6( g) 1(Mat) av(A) w
The display shows that Matrix A consists of two rows and three columns.
Since the result of the Dim command is list type data, it is stored in ListAns Memory.
You can also use {Dim} to specify the dimensions of the matrix.
Example 2 To specify dimensions of 2 rows and 3 columns for Matrix B
!*(  ) c,d!/(  ) a
K2(MAT) 6( g) 2(Dim)
6(g)1(Mat)al(B)w
• The “Dim” command can be used to check and configure vector dimension settings.
