clear
Remarks When you use clear in a function, it has the following effect on items in your
function and base workspaces:
2-266
• clear name -Ifname is the name of a function, the function is cleared in both
the function workspace and in your base workspace.
• clear functions - All functions are cleared in both the function workspace
and in your base workspace.
• clear global - All global variables are cleared in both the function
workspace and in your base workspace.
• clear all - All functions, global variables, and classes are cleared in both
the function workspace and in your base workspace.
Limitations clear does not affect the amount of memory allocated to the MATLAB process
under UNIX.
Examples Given a workspace containing the following variables
Name Size Bytes Class
c 3x4 1200 cell array
frame 1x1 java.awt.Frame
gbl1 1x1 8 double array (global)
gbl2 1x1 8 double array (global)
xint 1x1 1 int8 array
You can clear a single variable, xint, by typing
clear xint
To clear all global variables, type
clear global
whos
Name Size Bytes Class
c 3x4 1200 cell array
frame 1x1 java.awt.Frame
