Matrix Calculations | MAT |
The procedures in this section describe how to create matrices with up to three rows and three columns, and how to add, subtract, multiply, transpose and invert matrices, and how to obtain the scalar product, determinant, and absolute value of a matrix.
Use the Fkey to enter the MAT Mode when you want to perform matrix calculations.

Note that you must create one or more matrices before you can perform matrix calculations.
•You can have up to three matrices, named A, B, and C, in memory at one time.
•The results of matrix calculations are stored automatically into MatAns memory. You can use the matrix in MatAns memory in subsequent matrix calculations.
•Matrix calculations can use up to two levels of the matrix stack. Squaring a matrix, cubing a matrix, or inverting a matrix uses one stack level. See “Stacks” in the separate “User’s Guide” for more information.
kCreating a Matrix
To create a matrix, press Aj1(Dim), specify a matrix name (A, B, or C), and then specify the dimensions (number of rows and number of columns) of the matrix. Next, follow the prompts that appear to input values that make up the elements of the matrix.

2 rows and 3 columns
You can use the cursor keys to move about the matrix in order to view or edit its elements.
