The hp 39g+ deals very well with matrices. It offers many powerful tools as

well as a special MATRIX Catalog with full editing facilities.

The MATRIX Catalog

The MATRIX Catalog is entered by pressing

the MATRIX key (located above the 4). It

allows for the storage of ten matrices

(M1,M2,..M9,M0) which can be any size,

depending only on available memory. In the

example shown right, the catalogue contains

two matrices, a 3 x 3 and a 3 x 1. The reason

that the catalogue specifies that they are ‘real

matrices’ is that the hp 39g+ is capable of

storing and manipulating not only matrices of

real numbers but also matrices of real vectors,

complex numbers and complex vectors. The

key pops up the menu shown on the right, replacing the highlighted

matrix with any empty one of the new type that you specify. Press SHIFT

CLEAR to delete all.

Generally only the default type ‘real’ is required and, apart from small

exceptions, only those will be covered as the behavior is not significantly

different for others.

Matrices, like most other objects on the hp 39g+, can be sent to and received

from a computer or another hp 39g+ using the

and keys.

We’ll begin by entering a matrix into the

catalogue to practice simple editing. If there

are any matrices currently in the catalogue,

use SHIFT CLEAR to delete the whole

catalogue. Move the highlight to matrix M1 and

press the

key. The normal state for a

blank matrix is to contain nothing but a single zero, which is why they all

1 2 ... 165 166 167 168 169 170 171 172 173 174 175 ... 330 331
