Here is the caller graph for this function:

setVariableCount()

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.
