TMequation Struct Reference

Detailed Description

Matrix equation. This is basically an addition of transformation sequences (products) that must be equal to the identity (or to zero in some cases).

Each matrix equation defines a set of scalar equations according to the dof involved in the transformation product sequences. Typically there are 6 equations (the diagonal of the rotation part plust the translation) but they can be less if only one type of rotation is involved or one type of translation, etc).
