The output res is an index value for the ordered (either ascending or descending) list xVals so that for any x with min(xVals) <= max(xVals) the condition xVals[res] <= x <= xVals[res+1].

Syntax

Functions.hunt(x, {x1, x2, x3, ... xn}); // jsav = 1
Functions.hunt(x, {x1, x2, x3, ... xn}, jsav);

Implementation

The implementation closely follows that given in Press et al. [26, pp. 115-117]

Examples

hunt(1.9, {0,1,2,3,4}, 1); // 2
hunt(2.5, {3,2,1,0}, 1);   // 1
