This is inconsistent with most other integer-accepting APIs in numpy, which require these to be actual integers, and raise TypeError when they are not. The new behavior is: * Raise `TypeError` if the argument is a float, but not an integral one * Emit a `DeprecationWarning` if a float like `1.0` is passed, continuing to allow it its old meaning.

| |_|_|_|/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These fitting functions are all the same - the algorithm used does not care about the basis. This was done using: * A regex find / replace on all but poly and cheb * A manual diff showing that cheb differed only by whitespace * A manual diff showing that poly differed in `deg.ndim == 1` vs `deg.ndim > 0`. Given that this function only allows `deg.ndim <= 1`, and `ndim >= 0`, these two comparison are equivalent.

* | | | MAINT: Unify polynomial division functionsEric Wieser2019-03-127-80/+42
| | | | | | | | | | | | | | | | | | | | | | | | These division functions are all the same - the algorithm used does not care about the basis. Note that while chebdiv and polydiv could be implemented in terms of this function, their current implementations are more optimal and exploit the properties of a multiplication by a basis polynomial.
* | | | MAINT: Adjust variable names for consistencyEric Wieser2019-03-122-16/+16
| |_|/ |/| | | | | | | | | | | This makes the variable names in polydiv and chebdiv match polyutils._div. It also brings the order of the special-casing in line to match.

* | MAINT: Move duplicate implementations of ABCPolyBase._fromroots into polyutilsEric Wieser2019-03-117-90/+36
|/ | | | | | Every implementation is the same right now, other than calling different line / mul functions. Found by LGTM.
* MAINT: Merge duplicate implementations of `*vander2d` and `*vander3d` functionsEric Wieser2019-03-026-119/+59
| | | | | | | Every implementation is the same right now, other than calling a different `*vander` function. Merging these into a single private function taking a callback results in significant deduplication. Found by LGTM.
* MAINT: Fix ABCPolyBase in various waysEric Wieser2019-03-021-31/+46
| | | | | | | | | | | This previously: * Did not indicate the arguments in the abstract methods * Did not actually use the `abc` mechanism at all on python 3 (`__metaclass__` does not work any more) * Used the now-deprecated `@abstractproperty` This didn't cause any runtime problems, but does confuse LGTM, and was using the `abc` module incorrectly. This uses python3-only features of the abc module, so can't be backported.

| * BUG: polyval returned Non-Masked Arrays for Masked Input.Joachim Hereth2018-10-211-1/+14
| | | | | | | | | | | | | | | | This fix will preserve subtypes of ndarray when given as input (x) to the polyval function. In particular, the results for masked values of a masked array will be masked. Fixes #2477.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Choices made, and the alternatives rejected (for no particularly strong reason): 1. Show terms in ascending order, to match their internal representation * alternative: descending, to match convention 2. Shows 0 terms in gray * alternative: omit entirely * alternative: show normally to aid comparison 3. Write each term as `basis(ax + b) * alternative: write as `basis(u) ... where u = ax + b` * alternative: show the normalized polynomial In future it would perhaps make sense to expose these options to the end user
