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
