Hey!

I need to remove a parameter from workspace.. the parameter name is saved in a variable 'param_name' which is of course also in workspace. At a given moment I need to remove this parameter, but I can refer to it only by using my variable 'param_name'. How is this possible? I tried clearvars param_name but everybody knows that the result of this will be the removing of the variable 'param_name'.

Thanks! Diana

在 MATLAB Online 中打开

Use functional syntax

clearvars(param_name);

instead of command syntax.

And I got stuck... functions do not share the same workspace..

In my app I need to select a variable (which contains the name of a parameter from workspace) from a listbox (I sent this variable in workspace using assignin) and next I want to change the parameter name. After changing the name I want to delete from workspace the parameter which name is contained in the selected variable. All these steps are done in different functions. In my ChangeParameterName workspace function I don't have that parameter saved.

Is possible somehow to search in all "workspaces" that I have, from each function, and delete my parameter directly in this function where I change the name? Even if in this workspace ChangeParameterName function my parameter is not appearing?
