Coordinate Transformation of a-Matrix and alpha-Matrix

http://demonstrations.wolfram.com/CoordinateTransformationOfAMatrixAndAlphaMatrix The Wolfram Demonstrations Project contains thousands of free interactive visualizations, with new entries added daily. This Demonstration shows how coordinate systems are transformed and how the a-matrix and alpha-matrix are formed. There are four transformation options: rotation, rotation with inversion (roto-inversion), reflection, and inversion. The vector [h k l] de...
