Cubic_Spline_Table_Form(x_data, y_data)

Potential form that takes tabulated data and returns interpolated values.

class atsim.potentials.tableforms.Cubic_Spline_Table_Form(x_data, y_data)

Bases: object

Potential form that takes tabulated data and returns interpolated values.

This potential uses cubic spline interpolation. It is simply a wrapper around the scipy.interpolate.InterpolatedUnivariateSpline class

config_label = cubic_spline

is_potential = True

interpolant

This class is a wrapper around instances of scipy.interpolate.InterpolatedUnivariateSpline This property returns the scipy object used internally

__call__(self, x)

Returns:interpolated value at x

deriv(self, x)

Returns:derivative of potential form at x

deriv2(self, x)

Returns:second derivative of potential form at x
