SoVMRLTransform.setMatrix doesn't accept a parameter

[FredEPr]

I'm having an issue while trying to use the method setMatrix of the class SoVMRLTransform. It doesn't require any parameter:

n = pivy.coin.SoVRMLTransform()
help(n.setMatrix)

Help on method setMatrix in module pivy.coin:
setMatrix() -> 'void' method of pivy.coin.SoVRMLTransform instance
    setMatrix(SoVRMLTransform self)

If I try the same with the class SoTransform I get:

n = pivy.coin.SoTransform()
help(n.setMatrix)
Help on method setMatrix in module pivy.coin:

setMatrix(mat: 'SbMatrix') -> 'void' method of pivy.coin.SoTransform instance
    setMatrix(SoTransform self, SbMatrix mat)

This method requires a SbMatrix parameter.
I'm using pivy 0.6.6 in FreeCAD 0.20 on Windows 10.

I think it's a pivy issue because the setMatrix method in coin requires a parameter:
void setMatrix(const SbMatrix & matrix);
