compareTensors

Given two raw Saupe matrices specified in stdin, compute the normalized scalar product between the two tensors and the scalar product between axes. Also, compute angle of rotation between two axes.

Usage: compareTensors

Example:

compareTensors < tensors.in

where tensors.in contains two raw 3x3 Saupe matrices, e.g., as obtained from the calcTensor accessory program:

VarTensor   Saupe matrix:        7.030   17.274    1.159
VarTensor                       17.274  -23.343    2.768
VarTensor                        1.159    2.768   16.313
VarTensor   Saupe matrix:        2.481   18.246   -2.683
VarTensor                       18.246  -19.248    8.687
VarTensor                       -2.683    8.687   16.767
