Hi,as you do not give an example I can not be sure. But it sounds like the ever recurring problem of a function being evaluated with symbolic arguments. To ensure that the computations are done numerically, you may e.g. define: f[x_?NumericQ]:=...

When I run the code it takes a hell lot of time. I do not know what mathematica is doing inside, actually I have another code in fortran that takes only a few minutes to do all the calculations but there are other problems like it dosent work for some parameter range. > > Is there a method in which I can ask mathematica to give me only the numerical values just like any executable program does. > > Thanks. > TaB > -- Daniel Huber Metrohm Ltd.
