Limit the values of argument x to a particular range of values.

Usage
limit(x, lo, hi)
limitlow(x, lo)
limithigh(x, hi)
x
a scalar, vector or matrix
lo
lower boundary, must be a number
hi
upper boundary, must be a number
Result
The result r is a copy of x but the values of the elements of r are limited to the boundaries defined by lo and/or hi.
ri,j is set to lo if xi,j is lower than lo (functions limit and limitlow)
ri,j is set to hi if xi,j is greater than hi (functions limit and limithigh)

Example:

#a := eval vv(1,2,3,4,5,4,3,2,1)
#b := eval fill(9,0,1)
#c := eval limitlow($#a, 3)
// -> $#c = { 3 , 3 , 3 , 4 , 5 , 4 , 3 , 3 , 3 } 
#d := eval limit($#b, 2, 6)
// -> $#d[*,0] = { 2 , 2 , 3 , 4 , 5 , 4 , 3 , 2 , 2 }
//    $#d[*,1] = { 2 , 2 , 2 , 3 , 4 , 5 , 6 , 6 , 6 }
