public class FieldMatrixField
extends GenericMatrixField<java.lang.Object>

An MatrixField where elements are of type Object and the operation on elements are defined by a field. To set up use

    NumberFactory numf = new DoubleNumberFactory();
    DoubleField df = new DoubleField();
    MatrixFactoryI mfac = new FieldObjectMatrixFactory(df,numf);
    MatrixFieldI mf = new FieldObjectMatrixField(mfac,df);
    MatrixOperatorTable opTab = new MatrixOperatorTable(mfac, mf);
    MatrixFunctionTable mftab = new MatrixFunctionTable(mfac, mf);
    jep = new Jep(opTab,mftab);
