In regard to my master thesis I must implement an option pricing model by means of c++. I was looking for statistical functions which can help me but I could not find (e.g. a function which returns the cumulative normal distribution)
I thing it must be something like cmath but for other functions :) Or is there my be a header file which can be downloaded? (I was also looking for this but without result)
I wish people would stop thinking that downloading a header file automatically gives them code...
A header file just gives you the references and structures and macros required to know how to call a function. The .o, .lib, .a or .so (or maybe .dll) files that come in your compiler's lib/ folder (presumably) actually contained the code.
You can't just download a header file and everything is great. You need the object files.
