I did the profiling, and this line takes the most of time: running 28449740 times and takes 163.84s.
I am wonderring if there is any version that is faster than min.
[a,b]=min(c(s1,s2));

"... this line takes the most of time: running 28449740 times and takes 163.84s."
Sure. But there are several operations on that line, so how do you know that min is the slow one?

Reminder: extracting consecutive rows is faster than extracting consecutive columns, so you should consider transposing your array.
