* MAINT: Refactor polynomial leastsquares fits.Charles Harris2016-01-197-138/+105
| | | | | | | * Rewrite the documentation for `deg`. * Check that the passed degrees are int and raise if not. * Do not accept `deg` arguments that do not convert as 0-D or 1-D. * Sort passed degree terms for repeatability.

* ENH: Allow specification of terms to fit in hermefitJonathan Underwood2016-01-181-5/+34
| | | | | | | | | | The argument `deg` is enhanced to allow an array_like argument to past which specifies which terms to include in the fit. The returned coef array is exapnded to have entries of 0 for all coefficients which were not included in the fit.

* ENH: Take advantage of symmetry in leggauss.Andrew Dawson2015-06-191-1/+1
| | | | | | The calculation of points and weights for Gauss-Legendre quadrature can take advantage of the symmetry of the companion matrix when computing its eigenvalues in order to speed up the computation.

* MAINT: Improve computation of gauss weights for hermite and hermite_e.Charles Harris2014-10-042-14/+98
| | | | | | | | | | | | The new computations use normalized polynomials. Those polynomials are less subject to overflow and allow the determination of the weights and roots up to about degree 350, at which point the weights underflow. Two private functions are added for computing the values of the normalized polynomials: 1. _normed_hermite_n 2. _normed_hermite_e_n
* MAINT: Improve computation of scaled companion matrices.Charles Harris2014-10-042-6/+6
| | | | | | | | | The previous method used for hermite and hermite_e polynomials suffered from double overflow for polynomials of large degree. Those numbers were later scaled down by equally large numbers, but the result was NaN. The wanted values are now computed in such a way that overflow in some entries is replaced by underflow in others. The resulting zeros are a negligible perturbation of the companion matrix.

* MAINT: Comparison deprecation followup fixesSebastian Berg2014-05-042-4/+5
| | | | | | | Makes the identity check `a = np.array([np.nan], dtype=object)` `a == a`, etc. a deprecation/futurewarning instead of just changing it. Also fixes some smaller things.
* DEP: Deprecate that comparisons ignore errors.Sebastian Berg2014-05-041-3/+3
| | | | | | | | | | | | | | | | | | | | This means that for example broadcasting errors get raised. The array_equiv function is changed to explicitely test if broadcasting is possible. It may be nice to do this test differently, but I am not sure if that is possible. Create a FutureWarning for comparisons to None, which should result in areal elementwise (object) comparisons. Slightly adepted a wrong test. Poly changes: Some changes in the polycode was necessary, the one is probably a bug fix, the other needs to be thought over, since len check is not perfect maybe, since it is more liekly to raise raise an error. Closes gh-3759 and gh-1608

* MAINT: Refactor numpy/polynomial/_polybase.pyCharles Harris2014-05-031-121/+100
| | | | | | | | | | 1) Clean up the code and move repeated snippet to a method. 2) Remove use of has_sametype, has_samewindow, has_samedomain. I would like to deprecate those methods. 3) Fix error in __truediv__, and make it only allow non-boolean numbers for the denominator. Closes #4631.
