WebYou can replace names of functions using transformation rules: In [1]:= Out [1]= Any assignments you have made are used on function names: In [2]:= Out [2]= This defines a function which takes a function name as an argument: In [3]:= This gives Log as the function name to use: In [4]:= Out [4]= WebMathematica will be considerably faster and more powerful if you do that. Useful functions are Map[], and related functions. Also Nest and NestList will repeat operations. Many functions like RandomVariate will naturally produce a list of samples. (which can then be processed as a list and not used in a loop). I hope this helps. Regards
