Controlling Command Window Input and Output
So far, you have been using the MATLAB command line, typing functions and expressions, and seeing the results printed in the Command Window. This section describes
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 computes or saves them. Here are the different formats, together with the resulting output produced from a vector x
with components of different magnitudes.
x = [4/3 1.2345e-6] format short 1.3333 0.0000 format short e 1.3333e+000 1.2345e-006 format short g 1.3333 1.2345e-006 format long 1.33333333333333 0.00000123450000 format long e 1.333333333333333e+000 1.234500000000000e-006 format long g 1.33333333333333 1.2345e-006 format bank 1.33 0.00 format rat 4/3 1/810045 format hex 3ff5555555555555 3eb4b6231abfd271
If the largest element of a matrix is larger than 103 or smaller than 10-3, MATLAB applies a common scale factor for the short and long formats.
In addition to the format
functions shown above
suppresses many of the blank lines that appear in the output. This lets you view more information on a screen or window. If you want more control over the output format, use the sprintf
and fprintf
functions.
