    tsearch(tri, xi)

    Find simplices containing the given points. This function does the
    same thing as `Delaunay.find_simplex`.

    Examples
    --------

    >>> import numpy as np
    >>> import matplotlib.pyplot as plt
    >>> from scipy.spatial import Delaunay, delaunay_plot_2d, tsearch
    >>> rng = np.random.default_rng()

    The Delaunay triangulation of a set of random points:

    >>> pts = rng.random((20, 2))
    >>> tri = Delaunay(pts)
    >>> _ = delaunay_plot_2d(tri)

    Find the simplices containing a given set of points:

    >>> loc = rng.uniform(0.2, 0.8, (5, 2))
    >>> s = tsearch(tri, loc)
    >>> plt.triplot(pts[:, 0], pts[:, 1], tri.simplices[s], 'b-', mask=s==-1)
    >>> plt.scatter(loc[:, 0], loc[:, 1], c='r', marker='x')
    >>> plt.show()
