Struct matrix::Compressed
[−]
[src]
pub struct Compressed<T: Element> { pub rows: usize, pub columns: usize, pub nonzeros: usize, pub format: Major, 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-column format or
- the compressed-row format.
Fields
rows: usize
The number of rows.
columns: usize
The number of columns.
nonzeros: usize
The number of nonzero elements.
format: Major
The storage format.
data: Vec<T>
The values of the nonzero elements.
indices: Vec<usize>
The indices of rows for Major::Column
or columns for Major::Row
of
the nonzero elements.
offsets: Vec<usize>
The offsets of columns for Major::Column
or rows for Major::Row
such
that the values and indices of the i
th column for Major::Column
or
the i
th row for Major::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
.
