Name


    INDEX_OF_NEAREST_KPB

Purpose


    This function finds the index of the element of x whose value is
    nearest to x0. This is primarily useful for finding the index of

    element of the array that is closest to the latitude x0.
    If there are multiple elements in x that are the same distance from
    x0, this function returns the first one.

Category
