'clear all' doesn't clear certain variables

[nodal]

does any one ever encountered this problem? when i include 'clear
all' in my script(.m file) MATLAB is not clearing the variables
created by "assignin" command(it clears other variable though).
However, it clears everything when i type 'clear all' in command
window.

Any ideas why this is happening?

Thanks
Nodal.

It sounds like you're using functions. In that case everything you
do within your function stays within that function's workspace.
'assignin' sends the variable from the function to either the calling
function or the base workspace. When you call 'clear all' you are
only clearing the variables within the function workspace.

Look up the 'evalin' function.

Thanks for your reply. You are correct. I am using functions. I still
dont understand how to clear the base workspace from within the
function. The problem is even if i use the 'caller' as assignin ws
option, i cant clear the varibles as the variable are stored in
another functions scope. Any suggestions how to clear the base
workspace from with in the function?

Thanks

Yes, you need the evalin function:

evalin('base','clear all')

Thank you! That works.
