Package org.ojalgo.matrix.jama Description

This package contains adapter classes to Jama. The entire original Jama package is here but made package private. Use the adapters.

Instructions for the ojAlgo developer if/when Jama is updated:

1. Delete all *.java files in this package with names that do not begin with Jama*.
2. Move the new Jama files do this package and update the files' package declarations.
3. Change all the new classes from public to default (package private).
4. Apply fixes
   • Towards the end of the LU decomposition constructor the if statement((j < m) & (LU[j][j] != 0.0)) needs to be changed to ((j < m) && (LU[j][j] != 0.0)).
   • The getL() and getU() methods of the LU decomposition should be modified. Introduce a new parameter d that is the minimum of m and n. Use that to set the column dimension of L and the row dimension of U.
   • Add a package private method isSymmetric() that exposes the already existing field issymmetric in the EigenvalueDecomposition class.
   • Improve Matrix.times(): Move the declarations
     double[] Arowi;
and
double s;
     outside/before the loops to avoid excessive garbage creation.
