Method Detail

value

public abstract double value(double x,
                             double y)
                      throws FunctionEvaluationException

Deprecated.

Compute the value for the function.

Specified by:

value in interface BivariateRealFunction

Parameters:

x - Abscissa for which the function value should be computed.

y - Ordinate for which the function value should be computed.

Returns:

the value.

Throws:

FunctionEvaluationException - if the function evaluation fails.

fix1stArgument

public ComposableFunction fix1stArgument(double fixedX)

Deprecated.

Get a composable function by fixing the first argument of the instance.

Parameters:

fixedX - fixed value of the first argument

Returns:

a function such that f.value(y) == value(fixedX, y)

fix2ndArgument

public ComposableFunction fix2ndArgument(double fixedY)

Deprecated.

Get a composable function by fixing the second argument of the instance.

Parameters:

fixedY - fixed value of the second argument

Returns:

a function such that f.value(x) == value(x, fixedY)
