Type Alias SymbolicSparseColMatRef 

pub type SymbolicSparseColMatRef<'a, I, Rows = usize, Cols = usize> = SymbolicSparseColMat<Ref<'a, I, Rows, Cols>>;

symbolic view structure of sparse matrix in column format, either compressed or uncompressed

invariants

• nrows <= I::Signed::MAX (always checked)

• ncols <= I::Signed::MAX (always checked)

• col_ptrs has length ncols + 1 (always checked)

• col_ptrs is increasing

• col_ptrs[0]..col_ptrs[ncols] is a valid range in row_indices (always checked, assuming it’s increasing)

• if nnz_per_col is none, elements of row_indices[col_ptrs[j]..col_ptrs[j + 1]] are less than nrows

• nnz_per_col[j] <= col_ptrs[j+1] - col_ptrs[j]

• if nnz_per_col is some(_), elements of row_indices[col_ptrs[j]..][..nnz_per_col[j]] are less than nrows

soft invariants

• within each column, row indices are sorted in increasing order

note

some algorithms allow working with matrices containing unsorted row indices per column

passing such a matrix to an algorithm that does not explicitly permit this is unspecified (though not undefined) behavior
