Function Documentation

def IMP.test.numerical_derivative	(		func,
			val,
			step
	)

Calculate the derivative of the single-value function func at point val.

The derivative is calculated using simple finite differences starting with the given step; Richardson extrapolation is then used to extrapolate the derivative at step=0.

def IMP.test.xyz_numerical_derivatives	(		model,
			xyz,
			step
	)

Calculate the x,y and z derivatives of model's scoring function on the xyz particle.

The derivatives are approximated numerically using the numerical_derivatives() function.
