Arb has been merged into FLINT -- use https://github.com/flintlib/flint/ instead
acb_hypgeom_airy_bound can be improved: it blows up when z contains zero, and the formulas are probably more complicated than needed. Some explicit case splitting should be done to write z...
With mpmath as comparison: ``` sage: import mpmath sage: from sage.libs.mpmath.all import call as mpcall sage: mpcall(mpmath.legenp, 29/2, 0, 0) -0.145632776315886 sage: mpcall(mpmath.legenp, 31/2, 0, 0) 0.141013048084263 sage: mpcall(mpmath.legenp, 44/3,...
With Lambert's W implemented, it would be great to also have Wright's Omega function. See http://www.orcca.on.ca/TechReports/TechReports/2000/TR-00-12.pdf for a justification (by Corless and Jeffrey) for its use, and https://people.sc.fsu.edu/~jburkardt/c_src/toms917/toms917.html for an...
We're trying to upgrade flint-arb in Debian and running into this test failure: ~~~~ [..] gcc -Wdate-time -D_FORTIFY_SOURCE=2 -g -O2 -fdebug-prefix-map=$BUILD_PATH=. -fstack-protector-strong -Wformat -Werror=format-security -I$BUILD_PATH -I/usr/local/include -I/usr/local/include -I/usr/include test/t-evaluate_acb.c -o...
I just read your blog entry regarding rigorous numerical integration with ARB. This seems to be an amazing piece of additional functionality, and I am looking forward to the forthcoming...
Building the dependencies on windows is a pain and should be automated with a script.
The code can be based on the new multivariate polynomials in flint: https://github.com/wbhart/flint2/tree/trunk/fmpz_mpoly In particular, https://github.com/wbhart/flint2/blob/trunk/mpoly.h now defines useful common methods for implementing multivariate polynomials. This would have to be...
This issue is extremely similar to the one found in flint at https://github.com/wbhart/flint2/issues/330 touch: cannot touch ‘test/t-*.c’: No such file or directory touch: cannot touch ‘hypgeom/test/t-*.c’: No such file or...
I decided to build Arb in the new linux subsystem of Windows and when I did a make check, I got the following: CC ../build/fmpr/test/t-abs_bound_le_2exp_fmpz /tmp/ccyuIK39.o: In function `main': t-abs_bound_le_2exp_fmpz.c:(.text.startup+0x396):...
