Calculate the best estimate of intersection.
Calculates the best estimates of the intersection of two y-value
data sets that share a common x-value set.
x (array-like) – 1-dimensional array of numeric x-values
a (array-like) – 1-dimensional array of y-values for line 1
b (array-like) – 1-dimensional array of y-values for line 2
direction (string, optional) – specifies direction of crossing. ‘all’, ‘increasing’ (a becoming greater than b),
or ‘decreasing’ (b becoming greater than a). Defaults to ‘all’.
log_x (bool, optional) – Use logarithmic interpolation along the x axis (i.e. for finding intersections
in pressure coordinates). Default is False.
A tuple (x, y) of array-like with the x and y coordinates of the
intersections of the lines.
This function implicity converts xarray.DataArray to pint.Quantity, with the results
given as pint.Quantity.
