Workspace Variables
Theworkspacecontains variables that you create within or import into MATLAB®from data files or other programs. For example, these statements create variablesA
andB
in the workspace.
A = magic(4); B = rand(3,5,2);
You can view the contents of the workspace usingwhos
.
whos
Name Size Bytes Class Attributes A 4x4 128 double B 3x5x2 240 double
The variables also appear in the Workspace pane on the desktop.
Workspace variables do not persist after you exit MATLAB.Save your data for later use with thesave
command,
savemyfile.mat
Saving preserves the workspace in your current working folder in a compressed file with a.mat
extension, called a MAT-file.
To clear all the variables from the workspace, use theclear
command.
Restore data from a MAT-file into the workspace usingload
.
loadmyfile.mat
