I have already written a script that works perfect in Sage
(relaxation.py) but when I rename it (relaxation.spyx) to make it
faster it doesn't work because I got a message:
sage: attach relajacion.spyx
Compiling /home/cesarnda/Documents/SageProg/

_home_cesarnda_Documents_SageProg_service_relajacion_spyx_12.pyx:
31:20: undeclared name not builtin: zero_matrix
In the programming guide, it is said that ANY Script would work this
way. So I saw another example where a header (cimport
sage.rings.integer) was added. So, I tried to add
sage.matrix.constructor and it didn't work, I tried to add
sage.matrix.matrix_space and it didn't work either.
Could you tell where I can find a programming guide where this kind of
stuff is explained, because also this program works with 53-bit-
precision numbers.
