Définition

class RectBivariateSpline(BivariateSpline):

Description _{[extrait de RectBivariateSpline.__doc__]}

    Bivariate spline approximation over a rectangular mesh.

    Can be used for both smoothing and interpolating data.

    Parameters
    ----------
    x,y : array_like
        1-D arrays of coordinates in strictly ascending order.
    z : array_like
        2-D array of data with shape (x.size,y.size).
    bbox : array_like, optional
        Sequence of length 4 specifying the boundary of the rectangular
        approximation domain.  By default,
        ``bbox=[min(x), max(x), min(y), max(y)]``.
    kx, ky : ints, optional
        Degrees of the bivariate spline. Default is 3.
    s : float, optional
        Positive smoothing factor defined for estimation condition:
        ``sum((z[i]-f(x[i], y[i]))**2, axis=0) <= s`` where f is a spline
        function. Default is ``s=0``, which is for interpolation.
