PjPassedFunction

public PjPassedFunction(PuFunction function)

Construct a new PjPassedFunction.

Parameters:

function - the function to evaluate, number of functions must be equal to 1.

Method Detail

getNumOfVariables

public int getNumOfVariables()

Get the number of variables.

Specified by:

getNumOfVariables in class PnFunction

eval

public double eval(PdVector x)
