Piecewise function of several variables and how to display it
I need to define a piecewise function of several variables. For a function of one variable I would use probably
Piecewise. I would like to work with a function G of two variables t and s that is of this form:
def G(t,s): if (t < s): return 1 else: return 0
Although this works, I would like to have a nice displaying of this function, like a function generated by
Piecewise does. Is there another way how to define this function?
