impl PCA
fn default() -> Result<PCA, String>
default constructor
fn new_mat_max(data: &Mat, mean: &Mat, flags: i32, maxComponents: i32) -> Result<PCA, String>
the constructor that performs PCA
default value for arguments: - maxComponents: default 0

fn compute_var(&mut self, data: &Mat, mean: &Mat, flags: i32, retainedVariance: f64) -> Result<PCA, String>
fn project(&self, vec: &Mat) -> Result<Mat, String>
projects vector from the original space to the principal components subspace
fn project_to(&self, vec: &Mat, result: &Mat) -> Result<(), String>
projects vector from the original space to the principal components subspace
fn back_project(&self, vec: &Mat) -> Result<Mat, String>
reconstructs the original vector from the projection
fn back_project_to(&self, vec: &Mat, result: &Mat) -> Result<(), String>
reconstructs the original vector from the projection
