Detailed Description

One-dimensional closed interval class.

This is an example of how to use the Interval class:

using namespace mt;

// Some interval declarations
Interval in1;              // outputs as [0.0, 0.0]
Interval in2(1.0);         // outputs as [1.0, 1.0]
Interval in3(0.0, 2.0);    // outputs as [0.0, 2.0]
Interval in4(-1.0, 1.0);   // outputs as [-1.0, 1.0]
Interval in5(-0.5, -0.25); // outputs as [-0.5, -0.25]

// Tests and operations using intervals
bool test;
Scalar s;

test = isOverlap(in3, in4)   // true
test = isOverlap(in3, in5)   // false
test = isContained(1.0, in3) // true
test = isContained(in5, in4) // true
test = isContained(in5, in3) // false

in   = hull(in3, in5)        // in = [-0.5, 2.0]
in   = hull(in2, in5)        // in = [-0.5, 1.0]

in4.widen(1.0)               // in4 = [-2.0, 2.0]
s = in4.center()             // s = 0.0
s = in4.width()              // s = 4.0
