Struct DaeStructure 

pub struct DaeStructure {
    pub n_diff: usize,
    pub n_alg: usize,
    pub n_diff_eqs: usize,
    pub n_alg_eqs: usize,
    pub incidence: Vec<Vec<usize>>,
}

Incidence structure for a DAE system.

Describes which variables appear in which equations, partitioned into differential and algebraic variables.

Fields

n_diff: usize

Number of differential variables (y)

n_alg: usize

Number of algebraic variables (z)

n_diff_eqs: usize

Number of differential equations

n_alg_eqs: usize

Number of algebraic equations (constraints)

incidence: Vec<Vec<usize>>

Incidence: for each equation i, the set of variable indices it depends on. Variable indices 0..n_diff are differential, n_diff..n_diff+n_alg are algebraic.
