Start lookup tables.
sympy/integrals/meijerint.py:
(_create_lookup_table) New function.
(_mytype) New function.
(_lookup_table) New global variable.
(_rewrite_single) Use lookup tables.
sympy/integrals/tests/test_meijerint.py:
(test_lookup_table) New test.
TODO:
* cannot integrate exp(x)*Heaviside(1-x)
* cannot integrate many other things
* there is one test failure in integrals where I am not sure what to do
about
* there is a test in ode that needs updating (we can now do a new
integral)
* there is also an XFAIL test in integrals that we can now do (though
the answer
comes out different from what the test expects)
