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.

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)
