Modifications
19 April 2003 - PVr - added interface for vnl_matrix<T>
19 April 2004 - PVr - made 4x4 implementation a bit more robust (but still incomplete)
18 June 2004 - PVr - finally completed 4x4 implementation
19 June 2004 - PVr - added vnl_inverse_transpose() methods

| vnl_matrix_fixed<T,1,1> vnl_inverse | ( | vnl_matrix_fixed< T, 1, 1 > const & | m | ) |
Calculates inverse of a small vnl_matrix_fixed (not using svd).
This allows you to write e.g.
x = vnl_inverse(A) * b;
Note that this function is inlined (except for the call to vnl_det()), which makes it much faster than the vnl_matrix_inverse class in vnl/algo since that one is using svd.

Calculates transpose of the inverse of a small vnl_matrix_fixed (not using svd).
This allows you to write e.g.
x = vnl_inverse_transpose(A) * b;
Note that this function is inlined (except for the call to vnl_det()), which makes it much faster than the vnl_matrix_inverse class in vnl/algo since that one is using svd. This is also faster than using
x = vnl_inverse(A).transpose() * b;
