Editing structure fields using a MATLAB App

6 views (last 30 days)
Currently I am working on a project that requires an easy and user-friendly access to different variables, for this reason I am developing an app that simply allows to modify variables on the base workspace. The problem appears when structure fields are added, the assignin function prompts an error:
Error using assignin
Invalid variable name "Struct.Variable" in ASSIGNIN.
I would like to implement a method that can automatically evaluate all the variables in the base workspace preferably without using an auxiliary file. Furthermore I would also like to change the default values shown in the app layout whenever the values are changed using the Edit Field.
Thanks in advance

assignin() can only assign to complete un-indexed variables.
You will need to load the current struct into your workspace, modify the field, and assignin() the entire struct.
