Function zernike::projection_on_mask

pub fn projection_on_mask(
    surface: &[f64], 
    n_radial_order: u32, 
    n_xy: usize, 
    mask: &[f64]
) -> Vec<f64>

Surface decomposition

Returns the coefficients resulting of the projection of a surface on a complete set of n_radial_order orthonormalized Zernike modes defined on a regular grid n_xy X n_xy using the modified Gram-Schmidt algorithm, the surface is valid only on the mask defined with NaN values
