Methods

impl PtrOfDownhillSolver

pub fn as_raw_PtrOfDownhillSolver(&self) -> *mut c_void

pub unsafe fn from_raw_ptr(ptr: *mut c_void) -> Self

Trait Implementations

impl Algorithm for PtrOfDownhillSolver

fn as_raw_Algorithm(&self) -> *mut c_void

fn clear(&mut self) -> Result<()>

Clears the algorithm state

fn empty(&self) -> Result<bool>

Returns true if the Algorithm is empty (e.g. in the very beginning or after unsuccessful read

fn save(&self, filename: &str) -> Result<()>

Saves the algorithm to a file. In order to make this method work, the derived class must implement Algorithm::write(FileStorage& fs).

fn get_default_name(&self) -> Result<String>

Returns the algorithm string identifier. This string is used as top level xml/yml node tag when the object is saved to a file or string.

impl DownhillSolver for PtrOfDownhillSolver

fn as_raw_DownhillSolver(&self) -> *mut c_void

fn get_init_step(&self, step: &mut Mat) -> Result<()>

Returns the initial step that will be used in downhill simplex algorithm.

fn set_init_step(&mut self, step: &Mat) -> Result<()>

Sets the initial step that will be used in downhill simplex algorithm.

impl MinProblemSolver for PtrOfDownhillSolver

fn as_raw_MinProblemSolver(&self) -> *mut c_void

fn get_function(&self) -> Result<PtrOfFunction>

Getter for the optimized function.

fn set_function(&mut self, f: &PtrOfFunction) -> Result<()>

Setter for the optimized function.

fn get_term_criteria(&self) -> Result<TermCriteria>

Getter for the previously set terminal criteria for this algorithm.

fn set_term_criteria(&mut self, termcrit: &TermCriteria) -> Result<()>

Set terminal criteria for solver.

fn minimize(&mut self, x: &mut Mat) -> Result<f64>

actually runs the algorithm and performs the minimization.

impl Drop for PtrOfDownhillSolver

fn drop(&mut self)

Executes the destructor for this type.
