Struct matrix::Compressed

pub struct Compressed<T: Element> {
    pub rows: usize,
    pub columns: usize,
    pub nonzeros: usize,
    pub format: CompressedFormat,
    pub data: Vec<T>,
    pub indices: Vec<usize>,
    pub offsets: Vec<usize>,
}

A compressed matrix.

The storage is suitable for generic sparse matrices. Data are stored in one of the following formats:

• the compressed-row format or
• the compressed-column format.

Fields

rows: usize

The number of rows.

columns: usize

The number of columns.

nonzeros: usize

The number of nonzero elements.

format: CompressedFormat

The storage format.

data: Vec<T>

The values of the nonzero elements.

indices: Vec<usize>

The indices of columns (rows) of the nonzero elements.

offsets: Vec<usize>

The offsets of columns (rows) such that the values and indices of the ith column (row) are stored starting from data[j] and indices[j], respectively, where j = offsets[i]. The vector has one additional element, which is always equal to nonzeros, that is, offsets[columns] = nonzeros (offsets[rows] = nonzeros).
