To use a matrix in an expression, you can do any of the
following.
• Copy the name from the MATRX NAMES menu.
• Recall the contents of the matrix into the expression
with y [RCL] (Chapter 1).
• Enter the matrix directly (see below).
You can enter, edit, and store a matrix in the matrix editor.
You also can enter a matrix directly in an expression.
To enter a matrix in an expression, follow these steps.
1. Press y [ [ ] to indicate the beginning of the matrix.
2. Press y [ [ ] to indicate the beginning of a row.
3. Enter a value, which can be an expression, for each
element in the row. Separate the values with commas.
4. Press y [ ] ] to indicate the end of a row.
5. Repeat steps 2 through 4 to enter all of the rows.
6. Press y [ ] ] to indicate the end of the matrix.
Note: The closing ]] are not necessary at the end of an expression
or preceding !.
The resulting matrix is displayed in the form:
[[element1,1,...,element1,n],...,[elementm,1,...,elementm,n]]
Any expressions are evaluated when the entry is
executed.
Note: The commas that you must enter to separate elements are
not displayed on output.
