addpath() is only for use with directories, not individual files.

If you just want to execute the script, use run() -- but note that run() changes directories, so addpath() is better if you need to execute in the current directory.

Remember there is no point in using addpath() twice with the same path, so you may wish to check whether the target path is already on the path.

run namefile only works from command window...if i put in function callback i have this error whe i click on botton:

Someone can help me? I have this script but with run namefile doesn't start, unless i put it in command window...why?

[Walter Roberson]

Your script confuses base workspace with function workspace.

With run namefile something start because i can see an image:

 but the Workspace remains blank while i'm aspecting all the values that are in the script...like this

Your code does not match up. Your earlier error message was about SEQ001 on line 8 of poi5, but the code you show has a dir() at line 8, and so is clearly a completely different routine.

[Walter Roberson]

The variables *are* being created, in the workspace of pushbutton2_Callback, and so they disappear again as soon as that callback finishes executing.

If you need your script to put the variables in the base workspace, then have it specifically put them there, such as by using assignin()

By the way, your code uses constructs that haven't been necessary since MATLAB 5.

I solved that problem because before I had to do >>load (SEQ001.MAT) but now it's dynamic ,in fact there's no error in command window when i click on button.

I solved the problem with run namefile by doing the following thing:

Go to: D:\Programs\Matlab\toolbox\matlab\lang\run.m

#line 74 I change 'caller' to 'base'...I don't know if it's something very wrong but it works!!

I proved with assignin() but in my case i don't what i have to pass assignin('base','var',v) but if i want poi5??

By the way it works...now i would like to put (always in base Workspace) a variable from edit text through a push button..it doesn't work:

that's my gui:

and in pushbutton_Callback:
