Example 1 To assign 10 to the cell at row 1, column 2 of the following matrix:

12

Matrix A = 3 4

56

baaK2(MAT)1(Mat) av(A)!+(  )b,c

!-(  )w

Example 2 Multiply the value in the cell at row 2, column 2 of the above matrix by 5

K2(MAT)1(Mat) av(A)!+(  )c,c !-(  )*fw

uTo fill a matrix with identical values and to combine two matrices into a
single matrix[OPTN]-[MAT]-[Fill(]/[Augment]

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)6(g)3(Fill( )

d,6(g)1(Mat)av(A))w

Example 2 To combine the following two matrices:

A =

 

1

 

B =

 

3

 

 

 

4

 

 

2

 

 

 

 

 

 

 

 

K2(MAT)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.
