Chapter 9

Matrices and linear algebra

This chapter shows examples of creating matrices and operations with

matrices, including linear algebra applications.

Entering matrices in the stack

In this section we present two different methods to enter matrices in the

calculator stack: (1) using the Matrix Writer, and (2) typing the matrix directly

into the stack.

Using the Matrix Writer

As with the case of vectors, discussed in Chapter 8, matrices can be entered

into the stack by using the Matrix Writer. For example, to enter the matrix:

first, start the Matrix Writer by using „². Make sure that the option

@GO

→ is selected. Then use the following keystrokes:

2.5\` 4.2` 2`˜ššš

.3` 1.9` 2.8 `

2` .1\` .5`

At this point, the Matrix Writer screen may look like this:

5.01.02

8.29.13.0

0.22.45.2













−

1 2 ... 112 113 114 115 116 117 118 119 120 121 122 ... 174 175
