cugar::diff_var< ValType, 1, O > Struct Template Reference

Detailed description

template<typename ValType, uint32 O>
struct cugar::diff_var< ValType, 1, O >

Specialization of diff_var to scalar (i.e. 1-component) differentials This class allows to represent variables that carry an associated first-order differential (or gradient) with respect to a predefined set of variables.

Template Parameters

ValType	the value type of the expression
DiffType	the type of differential / gradient of the expression

#include <diff.h>

Public Types
typedef ValType	value_type
typedef diff_var< ValType, 1, O-1 >	diff_component_type
typedef diff_component_type	diff_type
