Sorry for the late replay...
In Python you can:
class MyExpr(Expression):
def __init__(self, func):
self.func = func
def eval(self, value, x):
value[0] = 0.0
feval = self.func(x)
if feval>0:
value[0] = feval
myexpr = MyExpr(func)
You can also make a compiled expression. See the docstring of
Expression, under bullet point 2, for this.
