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 scalar
- hi
- upper boundary, must be a scalar
- Result
- The result r has the same type as x but the values of r are limited to the boundaries defined by lo and hi.
- ri,j is set to lo if x
r[i] = yl{[i]}ifx[i] <= t{[i]}andr[i] = yh{[i]}ifx[i] > t{[i]}
- The result r has the same length as x.

Example:
#a := eval vv(1,2,3,4,5,4,3,2,1)
#b := eval fill(9,0,1)
#c := eval select($#a,3,0,$#a)
// -> $#c = { 0 , 0 , 0 , 4 , 5 , 4 , 0 , 0 , 0 }
#d := eval select($#a, $#b , $#b , $#a)
// -> $#d = { 1 , 2 , 3 , 4 , 5 , 5 , 6 , 7 , 8 }
#e := eval select($#b%2, 0, $#b, -1)
// -> $#d = { 0 , -1 , 2 , -1 , 4 , -1 , 6 , -1 , 8 }
Contents
limit
Limit the input values to a particular range of values.
Usage:
limit(val, lo, hi)
Function:
Limit the val values to the range of values between lo and hi (lo<=val<=hi). VAlues outside the range are set to the boundary values.
Parameters:
- val
- The input scalar, vector or matrix.
- lo
- The lower boundary scalar.
- hi
- The upper boundary scalar.
