App Designer - Acccess Data in Workspace?
显示 更早的评论
Hallo,
I have some data in the Workspace which I can access without any problems from the command window. However, if I try to call the variable in a callback function it does not work. It says that it is not recognizing a variable with such a name though the data is in the Workspace already.
How can I access the data which is already in the workspace in the appdesigner callback?
thanks.
regards
Erkan

The neatest, easiest, simplest, and by far the most efficient approach is to pass data as input/output arguments:
The MATLAB documentation clearly describes passing data as input/output arguments as "best practice".
Did you try passing the data as input/output arguments?

From the help:
Evaluate Variable Name in Base Workspace
Use the evalin function to get the value of a variable in the MATLAB base workspace and store it in a new variable.
Define var as the 5-by-5 matrix returned by the magic function.
var = magic(5);
Get the value of the variable var in the MATLAB base workspace and store it in the variable v.
v = evalin('base','var')
