Matrices

You can create, edit, and operate on matrices and vectors

in the Home view, CAS, or in programs. You can enter

matrices directly in Home or CAS, or use the Matrix Editor.

Vectors Vectors are one-dimensional arrays. They are composed

of just one row. A vector is represented by single brackets;

for example, [1 2 3]. A vector can be a real number

vector, or a complex number vector such as

[1+2*i 7+3*i].

Matrices Matrices are two-dimensional arrays. They are composed

of at least two rows and at least one column. Matrices

may contain any combination of or real and complex

numbers, such as:

or .

Matrix variables There are ten reserved matrix variables available, named

M0 to M9; however, you can save a matrix in a variable

name you define. You can then use them in calculations in

Home or CAS views or in a program. You can retrieve

matrix names from the Vars menu, or just type their names

from the keyboard.
