I looked for the built-in function before answering this question, but could not find it. But Le Wang need not write his own;

help mata range()

help mata rangen()

Thanks to Ben Jann for pointing that out.

Le Wang wonders why his Mata routine comes up one short some of the time. Just the usual finite-precision-arithmetic problem: remember that 0.1 is an irrational number in binary, so that adding it up 19 times does not necessarily give you exactly 1.90. Replace the line computing the number of points with n=ceil((to-from)/increment) +1 /* Number of points*/ and it should work.
