POLYC

Polynomial Classification

     W = polyc(A,CLASSF,N,S)

  INPUT
    A Dataset
    CLASSF Untrained classifier (optional; default: FISHERC)
    N Degree of polynomial (optional; default: 1)
    S 1/0, 1 indicates that 2nd order combination terms should be used
            (optional; default: 0)

Output
W	Trained classifier

Description

Adds polynomial features to the dataset A and runs the untrained  classifier CLASSF. Combinations of 2nd order terms may be constructed.  For higher order terms no combinations are generated.
