u Matrix Data Input Format [OPTN]-[MAT] -[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:
!a(CATALOG)a6(SYBL)4(9)
c~c( [ )w!a(CATALOG) ( [ )
1(INPUT)b,d,f
!a(CATALOG)c( ] )1(INPUT)
!a(CATALOG)f( [ )1(INPUT)
c,e,g
!a(CATALOG)c( ] )1(INPUT)
!a(CATALOG) ( ] )1(INPUT)!K(→)
K2(MAT)1(Mat)a1(A-E)1(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)
d!K(→)6(g)1(Mat)a
Number of rows/columns
1(A-E)1(A)w
u To check the dimensions of a matrix [OPTN]-[MAT] -[Dim]
Use the Dim command to check the dimensions of an existing matrix.
