This class was adapted from a class in the Kalman library written by Skip Carter (skip@taygeta.oc.nps.navy.mil
It performs the LU decomposition of a matrix. It can be used to find it's inverse and to solve linear systems.
This class can only be used with floating point values (float or double).
| void PLib::LUMatrix< T >::resize | ( | const int | r, | |

a destructive resize of the matrix dimensions
Changes the matrix dimensions and intialize it to 0.
| nr | the new number of rows | |
| nc | the new number of columns |
Reimplemented from PLib::Basic2DArray< T >.
