st: Generating a sequence of numbers in Mata |

Hi there, I have another question in Mata that I couldn't figure out. Suppose that I want to generate a sequence of numbers, equally spaced between ajacent numbers. mata drop seq() real vector seq(real scalar from, real scalar to, real scalar increment) { n=((to-from)+increment)/increment /* Number of points*/ x=J(n,1,0) for (i=1;i<=n;i++){ x[i,.]=from+increment*(i-1) } return(x) } This function works well when the end points are integers, but fails otherwise. In particular, the last point is always missing when the end points are NOT integers. Compare the following codes: x=seq(4,11,1) x=seq(4.2,6.1,.1) Can anyone tell me where I am wrong here? Many thanks.
