Enum JacobianMode 

pub enum JacobianMode {
    Sparse,
    Dense,
}

Controls which Jacobian assembly strategy the Problem uses.

Set this when constructing a Problem:

• Problem::new(JacobianMode::Sparse) — sparse (default, best for large-scale problems)
• Problem::new(JacobianMode::Dense) — dense (best for small-to-medium problems < ~500 DOF)
• Problem::default() — equivalent to JacobianMode::Sparse

The optimizer reads this field and dispatches to the appropriate assembly path. LinearSolverType selects the specific algorithm within the sparse path.

Variants

Sparse

Sparse Jacobian using symbolic structure and SparseColMat. Best for large problems.

Dense

Dense Jacobian using Mat<f64>. Best for small-to-medium problems (< ~500 DOF).

Trait Implementations

impl Clone for JacobianMode

fn clone(&self) -> JacobianMode

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for JacobianMode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for JacobianMode

fn default() -> JacobianMode

Returns the “default value” for a type.

impl PartialEq for JacobianMode

fn eq(&self, other: &JacobianMode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
