np.arange(8).reshape(2,4): This line creates a 1D NumPy array with integers from 0 to 7 and then reshapes it into a 2x4 2D array y.for a, b in np.nditer([x,y]):: This line initializes a loop using np.nditer to iterate over both arrays x and y simultaneously. Since x is...
The result for each group will be a DataArray with an entry for each element of the Cartesian product of that group's coordinates. I'm assuming the main issue here is to havecombine_by_coordsput a set of unnamed DataArrays into a single group and paste them together. ...
