While a calculation screen is on the display, you can input the Mat Ans variable by pressing z – {MATRIX}2(Mat)1-(Ans).

A Calculating the Scalar Multiplication of a Matrix

Your calculator supports the following types of scalar multiplication calculations. n × Mat A, n Mat A, Mat A × n, Mat A ÷ n

•You can replace “Mat A” with any of the calculator’s matrices, from Mat A to Mat F, or Mat Ans.

•For n, you can use a value, independent memory (M), variable, matrix name, constant (π or scientific constant), or scientific function value (like sin(30)).

Example: 3	×	2 0	+	1 2
		0 2		3 4

This example assumes that Mat A contains

3*(Mat A+Mat B)

A Absolute Values of Matrix Elements

The following determines absolute values of the elements of a matrix and places them onto the Mat Ans screen.

Example: To determine the absolute values of the matrix 15 –20 . This example assumes that Mat C contains 15 –20 .
