Struct ElimStep 

pub struct ElimStep {
    pub row: usize,
    pub var: usize,
    pub pivot: Number,
}

One accepted elimination, in application order.

The postsolve multiplier recovery in crate::linear_eq_elim walks these in reverse, which is what makes the dual system triangular; see that module’s recover_dropped_multipliers for why.

Fields

row: usize

Full-space row consumed by this step.

var: usize

Full-space variable it determined.

pivot: Number

The row’s coefficient on var in the partially substituted problem at the moment of the step — i.e. the pivot. Non-zero.
