MatrixInverse is incorrect #27

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
MatrixInverseEx generates correct results but MatrixInverse does not. I'm not 
sure why, but I inverted a view-proj matrix and multiplied and didn't get 
identity back with Inverse. I adapted a correct version of the implementation 
from Eberly:
http://www.geometrictools.com/LibMathematics/Algebra/Wm5Matrix4.inl
Which works as expected.

Forgot to mention, TransTransformBack may have a similar/related bug, but I'm 
not sure of the details.
