Source

pub fn compressedAxis(&self) -> SparseMatrixCompressedAxis

Which axis, row or column, is compressed

Source

pub fn indptrType(&self) -> Int<'a>

The type of values in indptrBuffer

Source

pub fn indptrBuffer(&self) -> &'a Buffer

indptrBuffer stores the location and size of indptr array that represents the range of the rows. The i-th row spans from indptr[i] to indptr[i+1] in the data. The length of this array is 1 + (the number of rows), and the type of index value is long.

For example, let X be the following 6x4 matrix:

  X := [[0, 1, 2, 0],
        [0, 0, 3, 0],
        [0, 4, 0, 5],
        [0, 0, 0, 0],
        [6, 0, 7, 8],
        [0, 9, 0, 0]].

The array of non-zero values in X is:

  values(X) = [1, 2, 3, 4, 5, 6, 7, 8, 9].

And the indptr of X is:

  indptr(X) = [0, 2, 3, 5, 5, 8, 10].
Source

pub fn indicesType(&self) -> Int<'a>

The type of values in indicesBuffer

Source

pub fn indicesBuffer(&self) -> &'a Buffer

indicesBuffer stores the location and size of the array that contains the column indices of the corresponding non-zero values. The type of index value is long.

For example, the indices of the above X is:

  indices(X) = [1, 2, 2, 1, 3, 0, 2, 3, 1].

Note that the indices are sorted in lexicographical order for each row.
