Matrix Calculation Examples
The examples here show the various input methods based on the following matrix addition:

Mat Ans
Mat Ans is a variable that stores the latest matrix calculation result. Any time a calculation result is in matrix
form, Mat Ans contents are overwritten that result. Whenever a matrix calculation result is a 1-row × n -column
or m -row × 1-column matrix, the contents of the
of that matrix calculation.
Calculation results less than 256 bytes are displayed on the Calculation tab, but calculation results equal to or
more than 256 bytes are displayed in the Ans window. While the Ans window is displayed, pressing b returns
to the Calculation tab with the result line displayed as "Mat Result".
Note
• Assigning a matrix variable to another matrix variable does not affect Mat Ans contents.
• If a matrix calculation result is too large to fit into Mat Ans, an error occurs.
Using the Matrix Tab
With the Matrix tab, you can edit matrix variables Mat A through Mat Z, and Mat Ans.
