Matlab can not (matlab is not good for anything symbolic or implicit anyway) but Mathematica definitely can plot such expressions. Why is interpolating a problem? All that you need to know is that your function is monotone on the interval on which you are working, thus just calculating one or two points inside your interval should be a good guess. Of course there will be pathological cases, but better fail only on patological cases than fail on every single expression that is more complicated than a combination of sin, sqrt and abs. Again, maybe I am missing something, but for the moment I do not see what it is. -- You received this message because you are subscribed to the Google Groups "sympy" group.
