I have a very tricky problem, I want to create an interpolation of a Step-Function. The problem is that the interpolation should keep the condition of area-preserving for every single step. This sounds like a histopolation, does it? Using Google (search: histopolation, histospline) had shown many theoretical abstracts but no Matlab-code. I found only a code-example for Mathematica but at all this is not working for me. (The spline is to "nervous"(rippled) for making a good interpolation)  

I hope you can give me an advice, how to make such an interpolation in Matlab. I would also be happy if you know a software which is able to do such an interpolation.

Best regards,
Paul M.
