How to use Signal Analyzer App inside of a script

Hello There,

I want to use the Signal Analyze App inside of a script.

This script loads a .mat file and then starts the signal Analyzer app

The Problem ist that the Workspace Browser of the Analyzer app shows no variables.

If I enter the code directly to the Command Window it works just fine.

I think the Problem is that the workspace refreshes only after the script ends.

How can I solve this problem?

Any Help is appreciated

I tried it with 'whos' and 'evalin' first which didnt work.

Assigning seems to solve this Problem.

 assignin('base', 'var', val) 

I dont know if this is the prober way, but for now I will keep it this way

Hello Honglei Chen,

The problem is that you cant operate with the app if there is no data to evaluate. You have to import the data via the app workspace browser first, but this is empty if you import the data and start the app within a MATLAB script.

With

assignin('base', 'var', val) 

I can now 'activate' the workspace and the data is visible in the app workspace browser, so that is working.

Thanks for your input.

Signal analyzer is capable of generating MATLAB script so you can run the script to accomplish what you did in the app. Maybe that's what you can use to achieve what you want?
