Hi all, just another small API announcement, that I merged:
https://github.com/numpy/numpy/pull/16154 which adds `symbol="x"` to the polynomial classes. Ross' more detailed explanation is copied below. Cheers, Sebastian New attribute ``symbol`` added to polynomial classes ---------------------------------------------------- The polynomial classes in the ``numpy.polynomial`` package have a new ``symbol`` attribute which is used to represent the indeterminate of the polynomial. This can be used to change the value of the variable when printing:: >>> P_y = np.polynomial.Polynomial([1, 0, -1], symbol="y") >>> print(P_y) 1.0 + 0.0·y¹ - 1.0·y² Note that the polynomial classes only support 1D polynomials, so operations that involve polynomials with different symbols are disallowed when the result would be multivariate:: >>> P = np.polynomial.Polynomial([1, -1]) # default symbol is "x" >>> P_z = np.polynomial.Polynomial([1, 1], symbol="z") >>> P * P_z Traceback (most recent call last) ... ValueError: Polynomial symbols differ The symbol can be any valid Python identifier. The default is ``symbol=x``, consistent with existing behavior.
