    Usage

    Initialization

    DynamicTimeWarping needs two arrays containing objects of the the same type and function that calculates the distance between two objects and returns a float.

    var ser1 = [ 9, 93, 15, 19, 24 ];
    var ser2 = [ 31, 97, 81, 82, 39 ];
    var distFunc = function( a, b ) {
        return Math.abs( a - b );
    };
     
    var dtw = new DynamicTimeWarping(ser1, ser2, distFunc);

    getDistance

    Will return the distance of the dynamic time warping as float.

    // 108
    var dist = dtw.getDistance();

    getPath

    Will return the path of the dynamic time warping as array of arrays with two integers.

    // [ [ 0, 0 ], [ 1, 1 ], [ 1, 2 ], [ 1, 3 ], [ 2, 4 ], [ 3, 4 ], [ 4, 4 ] ]
    var dist = dtw.getPath();
