I apologise if this question (or something like this) has been asked
earlier.
I have a slew of functions like :
f1[p1_,p2_,p3_]:= <some fn.>
f2, f3 similarly defined.
f5[x_,y_,z_]:=F(f1[..],f2[..],f3[..],f4[..]);
Now, this particular computation proceeds very slowly and I wish to speed
it up by compiling my functions. However, the very syntax of Compile
indicates that I cannot invoke a Compile'd function and pass arguments to
it.
For instance,
f1=Compile[{p1,p2,p3}, <some expression>] cannot be used in f5 above the
way I have been doing. Does this mean that I can only Compile f5 by itself
(with all the functions that it depends upon replaced by actual expression)
? If so, the resulting expression for f5 would be quite, quite complicated.
A little confused about this. And, yes, I haven't ever Compile'd a
Mathematica function.
Thanks.
