$[3]$ Your Problem

Create $n=6$ subintervals over $0,1$ :

i$)$ Find delta.x

ii$)$ Find all xi's over the interval:

$x1=0$

$x2=$ x$1+$ delta. $x$

Use a for loop:

iii$)$ Since: $x1=0($and was defined outside of the for loop$)$

iv$)$ Currently : $x=(x1,x2,x3,x4,x5,x6,x7\}$

v$),$ Create sub.low $=x[1$:$6]$ and sub.high $=x[2$:$7]$

vi$)$ Use command cbind$($ name, name$).$ For example sub $=$ cbind$($sub$.$low, sub.high$)$
