I would like to preallocate a array of 'track' object.

The problem is that: The 'track class' is inside my toolbox called 'mix'.

My toolbox path is: .../Documents/.../Mix Toolbox/+mix/@track/track.m

Here is the class:

classdef track < handle
    %TRACK Define the audio track object
    %   The track object will store the signal and
    %   all metadata of the audio file
    properties
        name
        signal
    end
    methods        
        function this = track(file)
            %CONSTRUCTOR Construct an instance of this class
            %   Init the track object:
            fprintf("Loading: %s \n", file.name);
            % Get the track name:
            this.name = file.name;
            % Read audio file:
            [this.signal, ~] = audioread(file.name);
        end
    end
end
