Storing Matrix Variables
When using matrix variables in calculations, you can store the necessary matrices for the calculation in matrix
variables Mat A to Mat Z as required. For example, if you want to calculate
1 3 2 6
in Mat A and
2 4 4 8
The number of both rows and columns of the matrix can be specified within 999.
Example: To store the 2-row × 2-column matrix
1. While the Calculation tab is active, press <.
• This displays the Matrix list on the Matrix tab.
2. Highlight [Mat A], and then select T > [Dimension].
3. In the dialog that appears, perform the following operation to specify
two rows and two columns: 2E2EO.
• This displays the Mat A input window.
4. Perform the following operation to enter the elements of the matrix:
1E3E2E4E.
5. Press b or O to return to the Matrix list.
To assign a matrix variable to another matrix variable
Example: To assign Mat A to Mat D, input "Mat A → Mat D" on the Calculation tab.
Note
• A matrix variable with 1 row and n columns or m rows and 1 column can be assigned to a vector
variable. For example, "Mat A → Vct A" assigns Mat A to Vct A.
To assign (overwrite) a value to a specific element of a matrix variable
Syntax: value being assigned → matrix name [row number,column number]
Example: To assign 40 to the element in row 2, column 2 of Mat A when Mat A =
To check the current contents of Mat A: V > [Matrix]
To recall the value of a specific element of a matrix variable
Syntax: matrix name [row number,column number]
Example: To recall the element at row 2, column 2 when Mat A =
V > [Matrix] > [Mat A]s4([)2`2s5(])E
in Mat B. Next, you can execute the operations Mat A + Mat B and Mat A − Mat B.
