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.
   • Add another constructor to EigenvalueDecomposition that takes an additional boolean parameter 'symmetric' as input, and does not test for symmetry.
   • SingularValueDecomposition: Make wantu and wantv input parameters to the existing constructor, and add another constructor with the old signature that sets both those parateres to true.
