Base class for all potentials
Derived classes must overload getEnergy(). It is also highly recommended to overload getEnergyGradient(), otherwise gradients will be calculated numerically
getEnergyGradient()
Methods
NumericalDerivative(coords[, eps]) | return the gradient calculated numerically |
NumericalHessian(coords[, eps]) | return the Hessian matrix of second derivatives computed numerically |
getEnergy(coords) | return the energy at the given coordinates |
getEnergyGradient(coords) | return the energy and gradient at the given coordinates |
getEnergyGradientHessian(coords) | return the energy, gradient, and Hessian at the given coordinates |
getEnergyGradientNumerical(coords) | |
getGradient(coords) | return the gradient at the given coordinates |
getHessian(coords) | return the hessian |
test_potential(coords[, eps]) | print some information testing whether the analytical gradients are correct |
