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

To fill a matrix with identical values and to combine two matrices into a
single matrix
[OPTN] - [MAT/VCT] - [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.

• 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.
