How to use data from App designer App drop downs and fields to populate variables in a script?

4 views (last 30 days)
I have a script that there are some variables that need to be set manualy before hand that contols time and angle etc. When the script is run it askes you to select a file to load that it will proccess and spit out another set of files. I would like to be able to have a front end gui that can be compiled stand alone to run on a laptop without Matlab. This app will have a button to load the file, fields and drop downs to populate the variables in the script.
I have the basic app layout done. The Load button works and the app returns to the top of the stack of windows on the screen. I have created parameters in App Designer for all the variables in the script that need populated. I am unsure how to pass the data from the App to the script. Or do I somehow move the script to the App. Untill all variables are populated in the script the script cannot be ran correclty.
thanks for any advice

You can't pass variables to a script directly. You can write a .mat file and have your script open it. But it's better to turn your script into a function. The function can be a separate m-file, or put into your app's .mlapp file.

Oh, it just added those because the original code was in GUIDE and it migrated it. I guess it just wnated to document that fact.
