Struct Shape

Source

pub struct Shape {
    pub joined: usize,
    pub closures: usize,
    pub adrift: usize,
}

Expand description

What the edges add up to.

Fields§

§joined: usize

How many nodes at least one edge touches.

§closures: usize

How many independent loops the edges form.

Zero is the number that matters. A survey with no closure is a tree: its residual is zero at whatever answer it gives, because no two measurements are ever compared, and every error made along the way is still in the answer.

§adrift: usize

How many joined nodes no chain of edges connects to the anchor.

Anything above zero makes the normal equations singular, and the survey has more than one piece.
