Function extendr_api::prelude::sparse::utils::adjoint_symbolic
pub fn adjoint_symbolic<'a, I>(
new_col_ptrs: &'a mut [I],

I: Index,
Expand description
Computes the adjoint of the symbolic matrix A
and returns a view over it.
The result is stored in new_col_ptrs
, new_row_indices
.
ยงNote
Allows unsorted matrices, producing a sorted output. Duplicate entries are kept, however.
