Discrete1DFunction

class openmm.openmm.Discrete1DFunction(*args)

This is a TabulatedFunction that computes a discrete one dimensional function f(x). To evaluate it, x is rounded to the nearest integer and the table element with that index is returned. If the index is outside the range [0, size), the result is undefined.

__init__(self, values) → Discrete1DFunction

__init__(self, other) → Discrete1DFunction

Create a Discrete1DFunction f(x) based on a set of tabulated values.

Parameters:

values (Sequence[float]) – the tabulated values of the function f(x)

Methods

Copy(self)	Create a deep copy of the tabulated function
__init__(-> Discrete1DFunction)	Create a Discrete1DFunction f(x) based on a set of tabulated values.
getFunctionParameters(self)	Get the parameters for the tabulated function.
getPeriodic(self)	Get the periodicity status of the tabulated function.
getUpdateCount(self)	Get the value of a counter that is updated every time setFunctionParameters() is called.
setFunctionParameters(self, values)	Set the parameters for the tabulated function.

getFunctionParameters(self)

Get the parameters for the tabulated function.

Returns:

values – the tabulated values of the function f(x)

Return type:

Sequence[float]

setFunctionParameters(self, values)

Set the parameters for the tabulated function.

Parameters:

values (Sequence[float]) – the tabulated values of the function f(x)

Copy(self) → Discrete1DFunction

Create a deep copy of the tabulated function

Deprecated

This will be removed in a future release.

__eq__(self, other) → bool

__ne__(self, other) → bool

getPeriodic(self) → bool

Get the periodicity status of the tabulated function.

getUpdateCount(self) → int

Get the value of a counter that is updated every time setFunctionParameters() is called. This provides a fast way to detect when a function has changed.
