limit, limitlow, limithigh

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 has the same type as x but the values of the elements of r are limited to the boundaries defined by lo and/or hi.

r_i,j is set to lo if x_i,j is lower than lo (functions limit and limitlow)

r_i,j is set to hi if x_i,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 }

<function list>

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.
