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 Editor, and (2) typing the matrix directly
into the stack.
Using the matrix editor
As with the case of vectors, discussed in Chapter 9, matrices can be entered
into the stack by using the matrix editor. 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:
