dominic jones:
I want to fill an array with random numbers without resorting
to loops, i.e. by doing something like the following, if it
were possible:
fill!(function double(){ return uniform(0.0, 1.0);})(x[]);
Is there a simple way of doing this?
Generally it's a good idea to use only pure functions inside the
higher order functions of Phobos. using impure functions like
uniforms could lead to bugs or performance problems.
This is a way to do it (untested):
x.copy(x.length.iota.map!(_ => uniform(0.0, 1.0));
