Struct ParameterSet 

pub struct ParameterSet {
    pub params: Vec<FitParameter>,
}

Collection of fit parameters for a forward model fit.

Fields

params: Vec<FitParameter>

All parameters (fixed + free).

Implementations

impl ParameterSet

pub fn new(params: Vec<FitParameter>) -> Self

pub fn n_free(&self) -> usize

Number of free (non-fixed) parameters.

pub fn free_values(&self) -> Vec<f64>

Get the values of all free parameters as a vector.

pub fn set_free_values(&mut self, values: &[f64])

Set the values of free parameters from a vector.

Panics

Panics if values.len() != self.n_free().

pub fn all_values(&self) -> Vec<f64>

Get the value of all parameters (fixed + free) as a vector.

pub fn all_values_into(&self, buf: &mut Vec<f64>)

Write all parameter values into the provided buffer, resizing if needed.

This is the buffer-reuse counterpart of all_values. Callers that fit many pixels in a loop can allocate one Vec<f64> and reuse it across iterations to avoid per-pixel allocation churn.

pub fn free_values_into(&self, buf: &mut Vec<f64>)

Write free parameter values into the provided buffer, resizing if needed.

This is the buffer-reuse counterpart of free_values. Callers that fit many pixels in a loop can allocate one Vec<f64> and reuse it across iterations to avoid per-pixel allocation churn.

pub fn free_indices(&self) -> Vec<usize>

Indices (into params) of free parameters.

pub fn free_indices_into(&self, buf: &mut Vec<usize>)

Write free parameter indices into the provided buffer, resizing if needed.

This is the buffer-reuse counterpart of free_indices. Callers that compute the Jacobian many times in a loop can allocate one Vec<usize> and reuse it across iterations to avoid per-call allocation.

Trait Implementations

impl Clone for ParameterSet

fn clone(&self) -> ParameterSet

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParameterSet

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

Formats the value using the given formatter.
