Classes
class	c2_exception
	the exception class for c2_function operations. More...
class	c2_composed_function_p< float_type >

class	c2_sum_p< float_type >
	create a c2_function which is the sum of two other c2_function objects.This should always be constructed using c2_function::operator+() More...

	create a c2_function which is the ratio of two other c2_functions.This should always be constructed using c2_function::operator/() More...
class	c2_piecewise_function_p< float_type >
	create a c2_function which is a piecewise assembly of other c2_functions.The functions must have increasing, non-overlapping domains. Any empty space between functions will be filled with a linear interpolation. More...

class	c2_classic_function_p< float_type >

Mostly useful for sampling into interpolating functions. construct a reference to this with c2_classic_function()The factory function c2_factory::classic_function() creates *new c2_classic_function_p() More...
class	c2_const_ptr< float_type >
	create a container for a c2_function which handles the reference counting.It is useful as a smart container to hold a c2_function and keep the reference count correct. The recommended way for a class to store a c2_function which is handed in from the outside is for it to have a c2_ptr member into which the passed-in function is stored. This way, when the class instance is deleted, it will automatically dereference any function which it was handed. More...

class	c2_cached_function_p< float_type >
	A container into which any other c2_function can be dropped.It allows a function to be pre-evaluated at a point, and used at multiple places in an expression efficiently. If it is re-evaluated at the previous point, it returns the remembered values; otherwise, it re-evauates the function at the new point. More...
class	c2_composed_function_p< float_type >
	Provides function composition (nesting)This allows evaluation of f(g(x)) where f and g are c2_function objects. More...
