                     java.util.ArrayList<java.lang.String> configuration)

Initialise symbolic calculations programically.

Parameters:

data - in form PND

configuration - . A list where strings representing conguration settings. Each parameter setting seprated by new line.

SymRegression

public SymRegression(PND xdata,
                     java.util.ArrayList<java.lang.String> configuration)
