* ENH: missingdata: Make numpy.all follow the NA && False == False ruleMark Wiebe2011-08-271-1/+1
|
* NEP: missingdata: Some fixes and updates to the NEPMark Wiebe2011-08-271-5/+17
|
* ENH: missingdata: Change default to create NA-mask when NAs are in listsMark Wiebe2011-08-271-7/+29
| | | | | Also adjust the repr to drop maskna=True when this rule will enable it automatically.
* ENH: missingdata: trying some more functions to see how they treat NAsMark Wiebe2011-08-271-2/+2
|
* ENH: missingdata: Add nastr= parameter to np.set_printoptions()Mark Wiebe2011-08-271-11/+15
|
* BUG: missingdata: Fix mask usage in PyArray_TakeFrom, add tests for itMark Wiebe2011-08-271-30/+25
|
* ENH: missingdata: Rewrote boolean indexing to support NA masksMark Wiebe2011-08-271-0/+32
| | | | Note I haven't hooked it up to the arr[] operator yet...
* ENH: missingdata: Have some basic assignment and indexing with NA workingMark Wiebe2011-08-271-5/+11

* ENH: missingdata: Add the NA mask members to PyArrayObjectMark Wiebe2011-08-271-2/+15

* STY: Updates for pull request feedback from Chuck and BenMark Wiebe2011-07-201-9/+124

* ENH: core: Deprecating direct access to the PyArrayObject fieldsMark Wiebe2011-07-191-8/+8
| | | | NOTE: WIP, code doesn't build
* NEP: missingdata: Rename 'namask' to 'maskna', which looks betterMark Wiebe2011-07-191-30/+40
|
* NEP: missingdata: Add a small note about single NA vs multi-NAMark Wiebe2011-07-081-0/+8
|
* NEP: missingdata: Describe a possible way multi-NA could be added in the futureMark Wiebe2011-07-081-0/+27
|
* NEP: missingdata: Change the mask definitionMark Wiebe2011-07-081-6/+17
| | | | | | | This change allows npy_bool to be a mask which always has payload zero. This doesn't let combining masks with payloads to be a simple 'min' operation as the previous design, but allowing npy_bool as the mask appears to be a very worthwhile tradeoff.
* NEP: missingdata: Design the mask binary format so it's extensible with a ↵Mark Wiebe2011-07-081-7/+21

* ENH: nditer: Add the per-operand masked iteration flagsMark Wiebe2011-07-081-0/+4

|
* NEP: missing-data: Add "Python API" and "C API" definitionsMark Wiebe2011-07-061-1/+13
|
* NEP: missing-data: Add numpy.ma to the glossaryMark Wiebe2011-07-061-1/+5
|
* NEP: missing-data: Add glossary of terms, try to clarify them betterMark Wiebe2011-07-061-28/+59
| | | | | This is a step towards having everyone on the list use the same vocabulary with specific nailed-down definitions for the terms.
* NEP: missing-data: Fix copy/paste/edit typo for np.all exampleMark Wiebe2011-07-061-6/+6
|
* NEP: missing-data: Incorporate Ben's feedback, add section on 'shared masks'Mark Wiebe2011-07-061-65/+107
| | | | This includes an email comment from Ben about 'np.any' and 'np.all'.
* NEP: missingdata: Rename 'hasmask' and friends to 'hasnamask' and friendsMark Wiebe2011-07-061-7/+46
| | | | | This is an attempt to reduce potential confusion between the existing numpy.ma and the NA-supporting built-in mask.

* ENH: umath: Add tests, work out kinks in ufunc 'where=' parameterMark Wiebe2011-07-061-0/+2
|
* ENH: umath: Add parsing of a 'where=' parameter in the element-wise ufuncMark Wiebe2011-07-061-8/+10
|
* ENH: missingdata: Move getting the masked ufunc inner loop to a different ↵Mark Wiebe2011-07-061-0/+1
| | | | | | | | | function This is so that backwards compatibility can be retained with denying regular ufuncs from supporting dynamic auxiliary data, but allowing it for the masked inner loops so that the default masked loop can store the regular inner loop it proxies calls to.
* ENH: missingdata: Add a mechanism to get masked versions of ufunc inner loopsMark Wiebe2011-07-061-2/+10
