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
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 looks like this:
Press ` once more to place the matrix on the stack. The ALG mode
stack is shown next, before and after pressing
`, once more:
