The format Function

The format function controls the numeric format of the values displayed by

MATLAB. The function affects only how numbers are displayed, not how

MATLAB co mputes or saves them. Here are the different formats, together

with the resulting output produced from a vecto r

x with components of

different m agnitudes.

Note To ensure proper spacing, use a fixed-w idth font, such as Courier.
