You can't have imperative code in a symbolic function, if that's what
you're asking. You can of course use an imperative (Python) function to
do what you want::
def s(m, a, t):
result = 0
for i in srange(1,m+1):
if i > a + t:
s += 2*i
else:
s += t
return result
But now this function cannot be used in some places where a symbolic
expression could. For example you will be hard pressed to plot a partial
evaluation of it without some wrapping gymnastics.
