Matlab error

    Hi lads

    I've wrote an M-file for a simulink block diagram I had drawn previously in which the variable "Zrear" was set as a simout to workspace block.

    In the Mfile I have a simple plot of Zrear versus time

    I keep getting the ??? Undefined function or variable "Zrear". error
    when I run the M-file even though the Zrear Variable is clearly defined in the block diagram.

    Has anyone ever had a similar problem or have any ideas? thanks



    p.s. I can post some of the M-file and a screenshot of the block diagram if needs be.

    Are you calling the Plot from a GUI you made with Matlabs GUI Editor (guide)? Or is everything in the same m-file?

    I used to have to re-declare the variables I was plotting or using in my GUI code when calling my functions.
