[sage-devel] Asymptotic Expressions in Sage

Hello everyone! I just wanted to let you know -- as suggested in https://groups.google.com/forum/#!topic/sage-devel/uR_bv7PrZpk -- that Clemens Heuberger, Daniel Krenn, and myself are currently working on improving the situation of asymptotic expressions in Sage. In order to do so, we have cre

[sage-devel] singular 4.0.1 upgrade: cython compile for 'plural' peeks wrong lib

[sage-devel] Re: singular 4.0.1 upgrade: cython compile for 'plural' peeks wrong lib

Now I tracked the issue down and solved it: libs for plural in 'src/module_list.py' were incorrect. Since I'm new to python/cython, i didn't knew that and grep for 'singular' was not an option (too many hits) Sorry for the noise. Jakob Am Donnerstag, 5. Februar 2015 13:38:34 UTC+1 schrieb Ja

How often do you think people want to compute the image under the identity map? If that is a common code path you could just have an cached is_identity() and check it before doing the matrix multiplication. Writing a specialization for a particular value precisely saves you that one check of a

Sorry, I press enter to fast. There is a coercion problem. The result of division of GF(5)['x'] by ZZ should live in GF(5)['x']. But right now the coercion model thinks that it should go to the fraction field... (see the example in my first mail). Is there a ticket related to that issue? Does anyb

[sage-devel] Re: flint-2.4.4 compile error for Sage-6.4 on MacOSX Mavericks

I can't shed much light on this. We do indeed call mpn_com_n from those flint functions. In flint.h mpn_com_n is #defined to mpn_com for compatibility with various versions of MPIR. The latter becomes xxxmpn_com where xxx can be g, _g, __g or ___g depending on the global symbol prefix on your

[sage-devel] Re: flint-2.4.4 compile error for Sage-6.4 on MacOSX Mavericks

Actually, we call mpn_com_n in flint. In flint.h this becomes mpn_com. In gmp.h in MPIR this becomes __MPN(com_n) which must be ___gmpn_com_n on your machine. If headers are included in the reverse order, mpn_com_n becomes directly ___gmpn_com_n in gmp.h. This is indeed the name of the symbol

Hi Set x=GF(5)['x'].gen() I dunno if this helps but here is an explanation why one gets a different behavior for x/7 than cm.bin_op(x,7,operator.div): If you do "x/7" then I think it calls __div__ from polynomial_element (Polynomial class): try: if not isinstance(right, Element) or right.pa

Cmake is a reverse approach compared to autotools. You need cmake installed to configure the software. The system to build (make or something else) is somewhat OS dependent. autotool generate a script and you don’t need auto tool installed on the target system. The main issue that you need to bo
