Hello,
Working again with the FDTD re-arrangement of terms, I am wondering if
there is any way to run collect() on indices of an IndexedBase object
using the current master sympy git repository. Rather than having (n+1)
expressed as a power, is it possible to run collect() in the manner
def generate_fdtd(expr, nsolve):
w = Wild('w')
expr0 = expr.lhs - expr.rhs
expr1 = expr0.expand()
# this doesn't work to collect terms at timestep (n+1)
print collect(expr1, p[w,w,n+1])
Pardon the unintentional indent, so the function should be:
def
