Variables become undefined although they are saved in Workspace

7 views (last 30 days)
I read XML file using GUI pushbutton, extract some data, and do some manipulations for them. The thing is although I save the required variables to workspace (using assignin), I can't use them outside the pushbutton callback function for further manipulation because matlab tells me 'undefined variables'! any suggestions? Thanks

Did you also define the workspace location?

If you just want to share data between callbacks then you shouldn't go through the base workspace at all, but I guess it works for you for now.
