Learn how to generate and use an Identity matrix on a graphing calculator (for example, in Input/Output analysis) (MATRIX/MATH/Identity).
- What is an identity matrix and how do you generate an identity matrix on a TI graphing calculator?
- How can you make a TI graphing calculator generate an identity matrix of specified dimensions for you?
- What does the MATH > identity function do on a TI graphing calculator?
This lesson shows you how to force a TI graphing calculator to generate an identity matrix for you, and all you have to do is specify the dimensions. This is a very useful tool so you do not have to manually enter the 1s and 0s yourself each time.
