* | BUG: fix typo on npy_config.h include guardJulian Taylor2013-06-032-2/+1
|/ | | | | Was overlooked as loops.c.src where np.isnan lives includes it directly. Now all isnan calls in numpy profit from the improvement.

* BUG: Handle a version string from a custom-built mingw64.mwtoews2013-05-292-1/+2
| | | | | | | | The custom build compiler "GNU Fortran (rubenvb-4.8.0) 4.8.0" was incorrectly parsed as version '-4.8.0' and the flag "-mno-cygwin" was added to the compilation. See http://cens.ioc.ee/pipermail/f2py-users/2010-October/002092.html.
* BUG: The npv function in financial.py was incorrectly implemented.bebert2182013-05-292-6/+6
| | | | | | | | | | | | | Correct the implementation of the npv function, its documentation, and the mirr function that depends on it. The test_financial.py is also corrected to take into account those modifications The npv function behavior was contrary to what the documentation stated as it summed indexes 1 to M instead of 0 to M-1. The mirr function used a corrective factor to get the correct result in spite of that error so that factor is removed. Closes #649

|\ | | | | ENH: Fix SyntaxError when matrix() is called with invalid string
| * ENH: Fix SyntaxError when matrix() is called with invalid stringLeon Weber2013-05-292-2/+15
| | | | | | | | | | | | | | | | | | | | | | | | The numpy.matrix constructor uses eval(str.translate(table)) to convert input strings to numeric matrix contents. str.translate(table) will return empty string if str consists only of invalid characters, causing SyntaxError in eval(). This is confusing, as one would expect an exception like TypeError when trying to construct a matrix from invalid input. This fix makes sure eval() is only called if str is not empty and TypeError is raised otherwise.

| | | | | | | | | | | | | | | | | | memmap needs to call it in __array_finalize__ to determine if it can drop the references on copies. The python version if may_share_memory caused significant slowdowns when slicing these maps. closes gh-3364

| * | | ENH: vectorize sqrt ufunc using SSE2Julian Taylor2013-05-2510-176/+417
| | |/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | specialize the sqrt ufunc for float and double and vectorize it using SSE2. improves performance by 4/2 for float/double if one is not memory bound due to non-cached data. performance is always better on all tested machines (amd phenom X2, intel xeon 5xxx/7xxx, core2duo, corei7) This version will not set errno on invalid input, but numpy only checks the fpu flags so the behavior is the same. In principle the compiler could autovectorize it when setting ffast-math (for no errno) and specializing the loop for the vectorizable strides and giving it some hints (restrict, __builtin_assume_aligned, etc.), but its simpler and more reliable to simply vectorize it by hand.
