Hi all. I was hoping someone cold help me. I wanted a way to apply
an arbitrary number of functions to an arbitrary number of sets of
arguments.
Meaning if I have n functions: {f1, f2, ...,fn} and m sets of
arguments: {x1, x2, ..., xm}, how can I generate a list like:
{{f1[x1], f1[x2], ...,f1[xm]},{f2[x1], f2[x2],
...,f2[xm]},...,{fn[x1], fn[x2], ...,fn[xm]}}?
I am currently doing this by looping throgh both lists and populating
each results one by one. As expecting this is horribly slow. I was
hoping someone could recommend a faster, functional way to do this. I
tried using map, but couldnt get a handle on it.
Any help would be greatly appreciated. Thank you in advance.
