Can we have an example on how to access psd data ?

How to access psd and expression information ?

1. How to get the PSD pose is triggered using which combination of inputs ?
   example: [browDownL + browLateralL]

2. How to get the translation values of boneX at psdY ?

The only information I can find are those:

getPSDCount() The number of distinct PSD expressions.
getPSDRowIndices() PSD(input) indices.
getPSDColumnIndices() Control(input) indices.
getPSDValues() Weights associated with each PSD row and column pair.

I see there is a PSDMatrix but I cannot find how to access it.

Thx
