How to declare Universal variable in GUIDE?
显示 更早的评论
I'm creating a GUIDE app that is supposed to load data and be able to plot 8 different regressions based off the data and display the plot in the GUI. The data is loaded by entering the filename into an editable text box, and clicking a button will read the data and put it into a matrix (using dlmread function). I'm not having trouble with this part. I then assign the x and y values to separate variables. Next, for example, clicking the linear regression function should plot the X vs Y. However, I can't get it to work because the x and y data variables are in the load button callback. In other words, I don't know how to use a variable created in one callback in another callback. Is there a way to make a global variable?

"Is there a way to make a global variable?"
Yes, but using global variables is a bad way to write code. Avoid using globals:
It is simple and much more reliable to use the standard methods for passing data between callbcaks, such as guidata, nested functions, etc.:
Search this forum for guidata for many examples of how to do this.
