Not understanding the error, why is abs not a function!

Hello,

im am writing a little App. It is a project for my schoolarship.

I want to create an rocker switch, which can create the fuzz sound and an overdrive sound.

But everytime i try to do it, it doesent work. Matlab brings always the same error. I have tried anonymous function, setting only a var for the val, create abs as a own function in my app and so....

Please someone helps me... I m really frustrated...

You're trying to call abs on the audioin property of your app, which is not a number but some sort of audio importing object. Try importing the audio data from that object then call abs on that data rather than the object.

Hej,

so i solved all these problems, but now i got a new one....

Why does it say, too many input arguments?

The funtion works fine, out of app designer.

And also i changed the input, it is not longer an audio file, i got the data, with uigetfile.

It is frustrating, please help me out!

Thany you alot!
