Struct MfaceCovResult 

#[non_exhaustive]
pub struct MfaceCovResult {
    pub block_cov: FdMatrix,
    pub grids: Vec<Vec<f64>>,
    pub offsets: Vec<usize>,
}

Multivariate FACE block covariance across several sparse variables.

Returned by mface_covariance. Carries the full (G_total × G_total) block covariance where G_total = Σ_p grids[p].len(). The block for variable pair (p, q) occupies rows offsets[p] .. offsets[p] + grids[p].len() and columns offsets[q] .. offsets[q] + grids[q].len() of block_cov. Diagonal blocks are the per-variable face_covariance; off-diagonal blocks are the cross-variable covariance (symmetric: block (q, p) is block (p, q) transposed). Use block to extract a sub-block.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

block_cov: FdMatrix

The full (G_total × G_total) block covariance matrix (column-major).

grids: Vec<Vec<f64>>

The per-variable evaluation grids (one per variable, in order).

offsets: Vec<usize>

Row/column start offset of each variable’s block: offsets[p] = Σ_{k<p} grids[k].len().

Implementations

impl MfaceCovResult

pub fn block(&self, p: usize, q: usize) -> FdMatrix

Extract the grids[p].len() × grids[q].len() covariance sub-block between variable p and variable q.

Panics

Panics if p or q is out of range (>= grids.len()).
