How to close a .mat file

Hello!

When loading a "*.mat" file i simply use load('foo.mat'), how can i close this file after loading it?

Thank you

[jacky chen]

it's a good question ,you maybe can load the *.mat in a subprogram, then you can return the variable and know which variable is in the *.mat, then use clear to delete them .

Thank you! Is it possible to create a blank mat file? Without loading the varibles in the workspace with it?

The load command should do that automatically. Load open the file, reads the data and closes the file aftwards. So there is no need for your to close it.

[jacky chen]

he maybe just wants to delete the variable from load..

[Walter Roberson]

In that case use

struct_name = load('foo.mat');

and refer to struct_name.VARIABLENAME instead of VARIABLENAME . Then

clear struct_name

to get rid of them all.

Also there is a button in the top panel, "Clear Workspace".
