Implementations

impl<'nrows, 'ncols, 'a, I, E> SparseColMatMut<'nrows, 'ncols, 'a, I, E>

where I: Index, E: Entity,

pub fn new( inner: SparseColMatMut<'a, I, E>, nrows: Size<'nrows>, ncols: Size<'ncols>, ) -> SparseColMatMut<'nrows, 'ncols, 'a, I, E>

Returns a new matrix view after checking that its dimensions match the dimensions tied to ('nrows, 'ncols).

pub fn into_inner(self) -> SparseColMatMut<'a, I, E>

Returns the unconstrained matrix.

pub fn values_of_col_mut( &mut self, j: Idx<'ncols, usize>, ) -> <<E as Entity>::Group as ForType>::FaerOf<&mut [<E as Entity>::Unit]>

Returns the values in column j.

pub fn symbolic(&self) -> SymbolicSparseColMatRef<'nrows, 'ncols, 'a, I>

Returns the symbolic structure of the matrix.

Methods from Deref<Target = SymbolicSparseColMatRef<'nrows, 'ncols, 'a, I>>

pub fn nrows(&self) -> Size<'nrows>

Returns the number of rows of the matrix.

pub fn ncols(&self) -> Size<'ncols>
