## Evaluate a Functional Data Object

### Description

Evaluate a functional data object at specified argument values, or evaluate a derivative or the result of applying a linear differential operator to the functional object.

### Usage

eval.fd(evalarg, fd, Lfd=0)

### Arguments

`evalarg ` |
A vector of argument values at which the functional data object is to be evaluated. |

`fd` |
A functional data object to be evaluated. |

`Lfd ` |
Either a nonnegative integer or a linear differential operator object. If present, the derivative or the value of applying the operator is evaluated rather than the functions themselves. |

### Details

### Value

Returns an array of 2 or 3 dimensions containing the function values. The first dimension corresponds to the argument values in evalarg, the second to replications, and the third if present to functions.
