Struct CalibrationMatrix 

pub struct CalibrationMatrix {
    pub name: String,
    pub rows: usize,
    pub cols: usize,
    pub data: Vec<f64>,
    pub input_unit: String,
    pub output_unit: String,
    pub calibration_timestamp: f64,
}

A labelled calibration matrix with row/column metadata.

Can represent misalignment corrections, scale-factor matrices, cross-axis coupling matrices, or any linear mapping used for sensor compensation.

Fields

name: String

Human-readable name (e.g., "accel_misalignment").

rows: usize

Number of rows.

cols: usize

Number of columns.

data: Vec<f64>

Elements in row-major order, length rows × cols.

input_unit: String

Unit string for the input quantities (e.g., "m/s²").

output_unit: String

Unit string for the output quantities (e.g., "m/s²").

calibration_timestamp: f64

Calibration date as a Unix timestamp in seconds.

Implementations

impl CalibrationMatrix

pub fn identity( name: impl Into<String>, rows: usize, cols: usize, input_unit: impl Into<String>, output_unit: impl Into<String>, ) -> Self

Create a new identity-like calibration matrix (diagonal 1, off-diagonal 0).

The matrix must be square (rows == cols) for the identity to make sense; for non-square matrices the main diagonal up to min(rows,cols) is set to 1.

pub fn get(&self, row: usize, col: usize) -> Option<f64>

Get element (row, col).

pub fn set(&mut self, row: usize, col: usize, value: f64) -> bool

Set element (row, col).

pub fn apply(&self, v: &[f64]) -> Option<Vec<f64>>

Apply the calibration matrix to input vector v (length == cols).

Returns None when v.len() != cols.

pub fn frobenius_norm(&self) -> f64

Frobenius norm of the matrix.

pub fn to_bytes(&self) -> Vec<u8>

Serialize to bytes.

Layout: [rows u64][cols u64][calib_ts f64][data… f64s] (name and units are not persisted in this binary format).

pub fn from_bytes(data: &[u8]) -> Option<Self>

Deserialize from bytes.
