WebAn array that has 1-D arrays as its elements is called a 2-D array. These are often used to represent matrix or 2nd order tensors. NumPy has a whole sub module dedicated … WebIf the goal is to get the best coefficients for a polynomial so it fits the given points, then a polynomial regression algorithm such as numpy.polynomial.polynomial.Polynomial.fit () will give you the best fit much faster, as there is an analytic solution to the polynomial least squares problem.
