compute method
Returns the y
value of the y = f(x)
equation where the function f
is
built by interpolating the given nodes nodes and x
is the given point
at which the function has to be evaluated.
Implementation
@override
double compute(double x) {
final node1 = nodes.first;
final node2 = nodes[1];
return node1.y +
(node2.y - node1.y) * ((x - node1.x) / (node2.x - node1.x));
}
