vice.toolkit.interpolation.interp_scheme_1d =========================================== A 1-dimensional interpolation scheme. This object takes in x-coordinates and y-coordinates of the same length and constructs a continuous function by connecting the points with straight lines. **Signature**: vice.toolkit.interpolation.interp_scheme_1d(xcoords, ycoords) .. versionadded:: 1.2.0 Parameters ---------- xcoords : array-like The attribute ``xcoords``. See below. ycoords : array-like The attribute ``ycoords``. See below. Attributes ---------- xcoords : ``list`` [elements are real numbers] The x-coordinates of the points to construct the interpolation scheme out of, in arbitrary units. .. note:: These values will be automatically sorted from least to greatest upon construction of an ``interp_scheme_1d`` object. While this could potentially alter the ordering of this attribute, it will not affect the ``ycoords`` attribute, which is assumed to correspond component-wise to the x-coordinates in their least to greatest ordering. ycoords : ``list`` [elements are real numbers] The y-coordinates of the points to construct the interpolation scheme out of, in arbitrary units. Calling ------- Call this object with a given x-coordinate, and it will automatically determine the correct pair of (x, y) coordinates to interpolate from, and return the appropriate value. Parameters: - x : real number The x-coordinate to evaluate the interpolation scheme at, in the same units as the attribute ``xcoords``. Returns: - y : real number The value of the y-coordinate, approximated via the line connecting the two points :math:`(x_1, y_1)` and :math:`(x_2, y_2)` such that :math:`x_1 \leq x \leq x_2`. If ``x`` is less than the smallest x-coordinate or larger than the largest one, the result will be determined via linear extrapolation using either the two smallest or two largest elements of the ``xcoords`` attribute. Indexing -------- Index this object as you would an array-like object, and it will return the (x, y) coordinates of the sampled points from the attributes ``xcoords`` and ``ycoords``.
