Read File Data in Signal Datastore

Specify the path to a set of audio signals included as MAT-files with MATLAB®. folder = fullfile(matlabroot,'toolbox','matlab','audiovideo'); Create a signal datastore that points to the specified folder and set sample rate variable name to Fs .

How do you find the inverse of a signal in MATLAB?

to flip the signal about the x-axis (negatives to positives and vice versa), simply use the function gnegate (x). Where X is the signal you're flipping.

What does '~' do in MATLAB?

Accepted Answer

This is the logical NOT operator, so ~isempty(E) will evaluate to true when E is not empty.
