Detailed Description

Base class of all automatic differentiation types.

This class records the number of independent variables with respect to which derivatives are computed.

Member Function Documentation

static size_t DiffScalarBase::getVariableCount ( )

inlinestatic

Get the variable count used by the automatic differentiation layer.

static void DiffScalarBase::setVariableCount ( size_t  value )

inlinestatic

Set the independent variable count used by the automatic differentiation layer.

This function must be called before doing any computations with DScalar1 or DScalar2. The value will be recorded in thread-local storage.
