Can someone help in finding code for solve function
Can someone help in finding code for solve function, i went through the source code but couldn't find it.

You can access the source code of the solve
function by typing, from a Sage shell:
sage: solve??
And then see which other function is called depending on the kind of input. Then you can iterate on what is actually called in your concrete example.
This is a linux machine, while running sage from in the terminal i was asking for...
sage: solve.__module__
'sage.symbolic.relation'
sage: t = sage.symbolic.relation
sage: t
<module 'sage.symbolic.relation' from '/usr/lib/sagemath/local/lib/python2.7/site-packages/sage/symbolic/relation.pyc'>
sage: t.__file__
'/usr/lib/sagemath/local/lib/python2.7/site-packages/sage/symbolic/relation.pyc'
And indeed, in the py-module for the above pyc-source one can find a line with def solve
:
dan@k7:~$ fgrep "def solve" /usr/lib/sagemath/local/lib/python2.7/site-packages/sage/symbolic/relation.py
def solve(f, *args, **kwds):
def solve_mod(eqns, modulus, solution_dict = False):
def solve_ineq_univar(ineq):
def solve_ineq_fourier(ineq,vars=None):
def solve_ineq(ineq, vars=None):
Similar steps should work on any other machine. For instance, after calling sage -sh (on linux) the location may be...
$SAGE_ROOT/local/lib/python2.7/site-packages/sage/symbolic/relation.py
with import_statements(solve)
, you'll get from sage.symbolic.relation import solve
, and this corresponds in the sage source tree to the file src/sage/symbolic/relation.py. other related commands are search_def
and search_src
.
