To help you started, the erf function is *Erf[z]* in Mathematica and it works over the complex field. In[1]:= Erf[1.5 - I] Out[1]= 1.0784+ 0.0279637 I Also, in addition to the introductory material available with any standard installation of Mathematica, you should read the following short articles: "How are the different brackets, such as {}, [], and () used in Mathematica?" http://support.wolfram.com/mathematica/kernel/features/brackets.html "Why doesn't sin[x] work in Mathematica?" http://support.wolfram.com/mathematica/kernel/features/casesensitive.html "What is the difference between =, ==, === in Mathematica?" http://support.wolfram.com/mathematica/kernel/features/differentequals.html "Why aren't my assignments and function definitions working?" http://support.wolfram.com/mathematica/kernel/features/assignments.html Regards, -- Jean-Marc
