Numarray is an array processing package designed to efficiently manipulate large multi-dimensional arrays. Numarray is modelled after Numeric and features c-code generated from python template scripts, the capacity to operate directly on arrays in files, arrays of heterogeneous records, string arrays, and in-place operation on memory mapped files. ========================================================================= Release Notes for numarray-1.5.0 I. ENHANCEMENTS 1. Implementation of scipy newcore array interface and __array_struct__ support (supplying and consuming) for numarray. This should facilitate better interoperability with scipy newcore and Numeric. This protocol is documented here: http://numeric.scipy.org/array_interface.html but also in numarray's source code in Include/numarray/arrayif.h. Thanks to everyone who gave feedback on 1.4.1 and particularly to Francesc Altet for his diligent testing (and doctest) of Numeric<->numarray data interchange. II. BUGS FIXED / CLOSED 1365121 Definition of PyObject* operator conflicts with C++ 1350954 nummacro.h:27: error: expected type-specifier before ';' tok 1346470 Please document more of what byteswap and byteswapped do 1364215 Cannot combine array and masked array (e.g. via divide) 1363723 my_array = +my_other_array uncovers a bug 1364811 Infinite loop converting empty CharArrays to lists 1364815 Strange behaviour when creating empty Int32 arrays 1340983 Fix __get_array_data__ 1346480 byteswapped doesn't match doc string 1346425 Please document if copy "fixes" byte order 1346426 Please document what array does with numarray arrays See http://sourceforge.net/tracker/?atid=450446&group_id=1369&func=browse for more details. III. CAUTIONS This release should be binary compatible with numarray-1.3.x. New extensions compiled against 1.5.0 may not work with prior versions of numarray.
