Matrix answer memory

On a Casio calculator matrix calculation results are automatically stored in the matrix answer memory.

 

---

Explanation

Whenever you perform a matrix calculation, the current matrix answer memory contents are replaced by the new result. The previous contents are deleted and cannot be recovered.

Inputting values into a matrix does not affect matrix answer memory contents.

When a matrix calculation result is m (rows) × 1 (column) or 1 (row) × n (columns), the calculation result is also stored in vector answer memory (VctAns).

Example 1

To transfer the contents of List 1 to column 1 and List 2 to column 2 of matrix answer memory Mat Ans

		LIST		L→M
OPTN		F1		F2	1	٬	2	Mat➔List(1,2		EXE

This gives for SET UP Input/Output Line

AnS 1 2 1 222 5.6 2 23 7.2 3 24 123.4   222

and for SET UP Input/Output Math

Mat➔List(1,2 222 5.6 23 7.2 24 123.4
