Hello everybody. I am really desperate because I do not succeed in simulating asset paths by monte carlo simulation. Somehow, everytime I am typing in the one of the following commands:
function SPaths=AssetPaths(S0,mu,sigma,T,NSteps,NRepl)
or
function SPaths=AssetPaths(S0,mu,sigma,T,NSteps,NRepl) or
paths=AssetPaths(...)
I get the following message:
??? function SPaths=AssetPaths(S0,mu,sigma,T,NSteps,NRepl) | Error: Function definitions are not permitted in this context.
Can someone please help me? Maybe I am missing the AssetPaths.m file?
Thanks for every answer
Kind regards dominic

You can declare a function only in a separate m. file and only as the very first line. So for example the following script will give the same error:
a = 10
function out = hi(a)
end

Minor variation: function must be the first non-blank non-comment line.

Thanks for the quick response. Unfortunately I still don't get, how I can make it work. Does your answer mean, that I cannot enter the function in the command window or in a script file?
I am currently using version 7.12.0 (R2011a).

Correct, you cannot enter function definitions at the command window or script file. You must put them in to a function .m file.

At the command window,
edit AssetPaths
and paste in the code and save the file as AssetPaths.m

You need to put the function AssetPath in a separate m-file that is named the same as the function.
eg: file 1: AssetPaths.m
function results = AssetPaths( ... )
statements
end
now you can invoke a call to AssetPaths on the command line like
>> paths = AssetPaths( ... input variables)

Is there any in-built function called "assetpaths"?
