Struct Projection 

pub struct Projection { /* private fields */ }

A split of a parameter vector into fixed and free entries.

Implementations

impl Projection

pub fn new( parameter_values: &Array, fix_parameters: Vec<bool>, ) -> QlResult<Self>

A projection of parameter_values, holding fixed every entry whose fix_parameters flag is true. An empty fix_parameters leaves every entry free.

Errors

Fails if fix_parameters is non-empty and its length differs from the seed, or if every entry is fixed (no free parameters remain).

pub fn project(&self, parameters: &Array) -> Array

Returns the subset of free parameters drawn from parameters.

Panics

Panics if parameters is not the size of the seed.

pub fn include(&self, projected_parameters: &Array) -> Array

Returns the full parameter vector, taking free entries from projected_parameters and reinstating the fixed entries from the seed.

Panics

Panics if projected_parameters is not the number of free parameters.

Trait Implementations

impl Clone for Projection

fn clone(&self) -> Projection

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Projection

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

Formats the value using the given formatter.
