Struct DenseMatrixSource 

pub struct DenseMatrixSource<'a, T: Scalar> { /* private fields */ }

Borrowed dense matrix source with column-major layout.

Wraps a column-major data slice for use with pivot kernels.

Implementations

impl<'a, T: Scalar> DenseMatrixSource<'a, T>

pub fn from_column_major(data: &'a [T], nrows: usize, ncols: usize) -> Self

Create a dense source from a column-major slice.
