2 Matrices and Arra ys

Entering Matrices

The best way for you to get started with MATLAB is to learn how to handle

matrices. Start MATLAB and follow a lo ng with each example.

You can enter matrices into MATLAB in several different ways:

• Enter an explicit list of elements.

• Load matrices from exte rnal data files.

• Generate matrices using built-in functions.

• Create matrices with your own functions in M-files.

Start by entering Dürer’s matrix as a list of its elements. You only have to

follow a few basic conve ntions:

• Separate the elements of a row with blanks or commas.

• Use a semicolon,

; ,toindicatetheendofeachrow.

• Surround t he entire list of elements with square brackets,

[].

To enter Dürer’s matrix, simply type in the Command Window

A=[163213;510118;96712;415141]
