Member Function Documentation

get()

double Mantid::CurveFitting::Algorithms::JacobianImpl::get ( size_t  iY, size_t  iP  )

inlineoverridevirtual

Get a value to a Jacobian matrix element.

Parameters

iY	:: The index of the data point.
iP	:: The index of the parameter. It does not depend on the number of fixed parameters in a particular fit.

Implements Mantid::API::Jacobian.

set()

void Mantid::CurveFitting::Algorithms::JacobianImpl::set ( size_t  iY, size_t  iP, double  value  )

inlineoverridevirtual

Set a value to a Jacobian matrix element.

Parameters

iY	:: The index of the data point.
iP	:: The index of the parameter. It does not depend on the number of fixed parameters in a particular fit.
value	:: The derivative value.
