GUI Neural Networks
in [Matlab]

From: Robert Shirley on 28 Feb 2010 18:11 I am trying to make a GUI that uses a FFBP network that I created. Whenever I run the GUI, it gives me a message '??? Undefined function or variable 'FFBP'. Of course everything beyond that is also an error. The network, which I called FFBP, is in my workspace and current directory. Can someone please tell me what I have to do to get the GUI to recognize my network. Thank you

Is FFBP a variable, a file with the extension .m, or both? Like all functions, GUI callback functions generally operate in their own workspace that is distinct from the base workspace (the workspace in which the command line operates.) Thus if FFBP is a variable in the base workspace, the callback functions cannot "see" it. You would need to get the variable into the function workspace somehow (either by passing it in as an input argument, or by storing it as a property of one of the GUI's components from which you can retrieve it inside the function, etc.) -- Steve Lord slord(a)mathworks.com comp.soft-sys.matlab (CSSM) FAQ: http://matlabwiki.mathworks.com/MATLAB_FAQ
From: Robert Shirley on 4 Mar 2010 15:47 Thank you for your response. FFBP was a neural network. I gather networks are treated differently from variables or other functions. I did not recognize GUI's operate with its own workspace. When I understood this, then I found the 'load' function which was able to bring my 'FFBP' function into the GUI's workspace. Thank you again.
