Undo "import"

I use the robotic toolbox from: http://petercorke.com/wordpress/toolboxes/robotics-toolbox

There I use

import ETS3.*

Later when i try:

simplify(something,'steps',10)

There is an errormessage:

Error using RTBPose/simplify Too many input arguments.

So i guess the import-command is somehow overloading the simpify-command. Can I undo the import, command?

Something like:

clear ETS3.*    %this does not help

For the sake of solving you can write a function with a different name with same parameters and inside that function, call the simplify function and return the result.

I tried:

function outputArg1 = mysimplify(input,steps)
    outputArg1 = simplify(input,'steps',steps);
end

then in the main code:

mysimplify(something,10);

But I got still the same error-message.

You probably want this:

clear import

That will clear all imports (not just 'ETS3.*').

If you only want to clear the import of 'ETS3.*' and keep other imports, you'll have to do something clever, maybe like this:

I = setdiff(import, 'ETS3.*');
clear import;
cellfun(@import, I);

In case that code is hard to follow, here is a slightly longer, clearer version that does the same thing:

I = import;
clear import;
I = setdiff(I, 'ETS3.*'); % remove 'ETS3.*' from I
for i = 1:numel(I)
    import(I{i});
end

(If this seems awkward, and you need to do this a lot, consider submitting a bug report/feature request to MathWorks Support.)

One other note: This only works from the command prompt. Within a function, you can't use clear import. But the imports are removed at the end of the function.
