Hi, You gave RealList as head of ns > :Begin: > :Function: writesample > :Pattern: WriteSample[filename_String, ns_RealList] (* !!!! That's Your problem *) > :Arguments: {filename, ns} > :ArgumentTypes: {String, RealList} > :ReturnType: Integer > :End: > This pattern will never match because Mathematica has no RealList data type. In fact You must say :Pattern: WriteSample[filename_String,ns_ /; VectorQ[ns,Real]] ns has the head List[] and not RealList or what ever. RealList is a ``type'' for mprep -- not for Mathematica. Hope that helps Jens
