{{alias}}( t, λ )
    Evaluates the moment-generating function (MGF) for an exponential
    distribution with rate parameter `λ` at a value `t`.

    If provided `NaN` as any argument, the function returns `NaN`.

    If provided a negative value for `λ`, the function returns `NaN`.

    Parameters
    ----------
    t: number
        Input value.

    λ: number
        Rate parameter.

    Returns
    -------
    out: number
        Evaluated MGF.

    Examples
    --------
    > var v = {{alias}}( 2.0, 3.0 )
    3.0
    > v = {{alias}}( 0.4, 1.2 )
    1.5
    > v = {{alias}}( 0.8, 1.6 )
    2.0
    > v = {{alias}}( 4.0, 3.0 )
    NaN
    > v = {{alias}}( NaN, 3.0 )
    NaN
    > v = {{alias}}( 2.0, NaN )
    NaN


{{alias}}.factory( λ )
    Returns a function for evaluating the moment-generating function (MGF) for
    an exponential distribution with rate parameter `λ`.

    Parameters
    ----------
    λ: number
        Rate parameter.

    Returns
    -------
    mg: Function
        Moment-generating function (MGF).

    Examples
    --------
    > var myMGF = {{alias}}.factory( 4.0 );
    > var y = myMGF( 3.0 )
    4.0
    > y = myMGF( 0.5 )
    ~1.143
