Example 1 To assign 10 to the cell at row 1, column 2 of the following matrix:
Matrix A =
baaK2(MAT/VCT) 1(Mat)
av(A) !+( ) b,c
!-( ) w
• The "Vct" command can be used to assign values to existing vectors.
Example 2 Multiply the value in the cell at row 2, column 2 of the above matrix by 5
K2(MAT/VCT) 1(Mat)
av(A) !+( ) c,c
!-( ) *fw
• The "Vct" command can be used to recall values from existing vectors.
u To fill a matrix with identical values and to combine two matrices into a
single matrix
Use the Fill( command to fill all the cells of an existing matrix with an identical value and the
Augment command to combine two existing matrices into a single matrix.
Example 1 To fill all of the cells of Matrix A with the value 3
K2(MAT/VCT) 6( g) 3(Fill( )
d,6( g) 1(Mat) av(A)) w
• The "Fill" command can be used to write the same value into all vector elements.
Example 2 To combine the following two matrices:
Matrix A = Matrix A =
K2(MAT/VCT) 5(Augment)
1(Mat) av(A) ,
1(Mat) al(B)) w
• The two matrices you combine must have the same number of rows. An error occurs if you
try to combine two matrices that have different number of rows.
• You can use Matrix Answer Memory to assign the results of the above matrix input and edit
operations to a matrix variable. To do so, use the following syntax.
Augment (Mat α , Mat β ) → Mat γ
In the above, α , β , and γ are any variable names A through Z.
The above does not affect the contents of Matrix Answer Memory.
• The "Augment" command can be used to merge two vectors into a single matrix.
