(2) "Ans" stands for "MatAns".
Note: "MatAns" stands for "Matrix Answer Memory". See "Matrix Answer
Memory" for more information.
7. Perform the next calculation (MatA+MatB):
(MATRIX) (MatA) (MATRIX) (MatB) .
Matrix Answer Memory
Whenever the result of a calculation executed in the MATRIX Mode is a
matrix, the MatAns screen will appear with the result. The result also will
be assigned to a variable named "MatAns".
The MatAns variable can be used in calculations as described below.
• To insert the MatAns variable into a calculation, perform the following
key operation: (MATRIX) (MatAns).
• Pressing any one of the following keys while the MatAns screen is
displayed will switch automatically to the calculation screen: , ,
, , , , (x
3
). The calculation screen will show the
MatAns variable followed by the operator or function for the key you
pressed.
Assigning and Editing Matrix Variable Data
Important!
• The following operations are not supported by the Matrix Editor: , (M-),
(STO). Pol, Rec, ÷R, and multi-statements also cannot be input with the
Matrix Editor.
To assign new data to a matrix variable:
1. Press
(MATRIX) (Dim), and then, on the menu that
appears, select the matrix variable to which you want to assign data.
2. On the next menu that appears, select dimension (m×n).
3. Use the Matrix Editor that appears to input the elements of the matrix.
