Matrix functions matr(ix)_inv(erse)

• matr_inv(point_att)

The matr_inv(point_att) function calculates the invertible matrix of the point_att argument with the same resulting domain unit as of the point_att argument.

The value type of the resulting attribute is the same as the value type of the point_att argument.

• attribute point_att with float32 or float64 value type

1. The value type of point_att and of the resulting attribute need to match.
2. The domain unit of point_att and the resulting attribute must match and be a Point value type of the group CanBeDomainUnit.
