SVG.js: Animate matrix via morph() method

Question

I would like to animate a transform matrix using SVG.js. There is a method listed, matrix.morph(), that is intended to do this. I can't make this happen.

Below is an example that attempts to apply this method, but it does not do anything. Could someone please show me how to animate a transform matrix using SVG.js. Thanks.

    var mySVG = SVG('svgDiv').size(400, 400);
    var myRect = mySVG.rect(100,100).attr({x:150,y:150,id:'myRect',fill: '#f00','stroke-width':3,stroke:'black'});
    var myRectMatrix = new SVG.Matrix
    var myRectMatrixMorph=myRectMatrix.morph(1,2,3,4,5,6)
    console.log(myRectMatrixMorph.toString())

To animate the transformation of an element you do it the same way as setting a transform on the element - with the transform() method. You dont need to touch the morph methods yourself when animating.

Try:

el.animate().transform({rotation:25})
// or with matrix
el.animate().transform({a:1, b:0, c:0 .... })
// or with SVG.Matrix
el.animate().transform(new SVG.Matrix(1,0,0 ....))

The morph method is only for the case you want a matrix at a specific position. Like:

var m1 = new SVG.Matrix(1,0,0,1,0,0)
var m2 = new SVG.Matrix(2,0,0,2,0,0)
m1.morph(m2)
m1.at(0.5) // returns matrix (1.5,0,0,1.5,0,0)
