Alternatively, you can implement this will the append operator:
fun float[] t(float x,float nn[]) {
// assign with zero length
float rr[0];
for(0 => int n;n<nn.size();n++) {
// append
rr << (nn[n] + x );
}
return rr;
}
<<< t(4.5, [7.,8.,9.])[2] >>>; // should print 13.5

Yes, ditto to what Kassen said. (I'm too slow... ;)
fun float[] t(float x,float nn[]) {
float rr[nn.size()];
for(0 => int n;n<nn.size();n++) {
nn[n] + x => rr[n];
}
return rr;
}

David,
I think the problem may be that you are returning an array that is local to
your function and it is getting deallocated when the function returns.
That's what I thought too, and that certainly can happen.
In that case a extra assignment (using @) can increase the reference
count, tricking the simple CC. That's not "good form" just a
workaround while some of that stuff is a bit dodgy.
That's not the issue here though, at least not the primary one. The
primary issue here is that rr gets defined without a length and so
apparently doesn't get initiated. Editing the relevant line to read;
float rr[nn.size()];
makes sure all floats are initiated and for my tests it works.
I think the issue is not with returning, the reported error is
refering -I suspect- to the moment when we try to chuck the result of
the addition to the array location, the error just isn't indicating
that, obfuscating what went wrong.
I hope that helps (I also hope it's correct ;-) )
Yours,
Kas.
