Struct BlockSparseFactor 

pub struct BlockSparseFactor {
    pub variables: Vec<String>,
    pub cardinalities: Vec<usize>,
    pub block_size: usize,
    /* private fields */
}

Block-sparse factor for factors with block structure.

Efficient when non-zero entries are clustered in blocks.

Fields

variables: Vec<String>

Variable names

cardinalities: Vec<usize>

Cardinalities

block_size: usize

Block size
