Inputting a Matrix into a Calculation
To use a matrix, you can use any one of the methods described below to input it into a calculation.
Method 1: Using the name of the matrix variable
Example: To input "Mat A"
Note
• You can input either an upper-case X (P+(X)) or lower-case x (X) for matrix variable "Mat X".
Both "Mat X" and "Mat x " refer to the same matrix variable.
Method 2: Using a template
A matrix with up to 6 columns and 6 row can be input using a template.
Example: To input the 2-row × 2-column matrix
1. While the Calculation tab is active, select T > [m×n].
2. In the dialog that appears, perform the following operation to specify
two rows and two columns: 2E2EO.
• This displays a 2-row × 2-column template.
3. Use the template to enter values.
Method 3: Using linear input form
To input this:
m -row × n -column matrix
The maximum value of both m and n is 999.
Example: To input the 2-row × 2-column matrix
Using Matrices in Calculations
Your calculator supports the types of matrix calculations.
• Addition, subtraction, and multiplication of two matrices, and scalar multiplication, squaring, powers, absolute
value, and complex number calculations of a single matrix.
These types of calculations are performed by entering matrices and operators. Examples of how to perform
these calculations are provided below.
• Matrix inversion, determinant, matrix transposition, identity matrix, row echelon form of a matrix, reduced row
echelon form of a matrix.
For these calculations, see the
Note
• The calculation precision of displayed results for matrix calculations is ±1 at the least significant digit.
