[Fill]/[Aug]
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.
Fill (
n
, Mat
α
)
Augment (Mat
α
, Mat
β
)
→
Mat
γ
In the above,
α
,
β
, and
γ
are any variable names A through Z, and
n
is any value.
The above does not affect the contents of Matrix Answer Memory.
