Common methods for blocks of a Hessian.

Required Methods

fn entry(&self, row: usize, column: usize) -> TensorRank0

The entry of the block at the given row and column within it.

fn height(&self) -> usize

The number of rows the block occupies.

fn width(&self) -> usize

The number of columns the block occupies.

fn fill_into_block<M>(&self, matrix: &mut M, row: usize, column: usize)

where M: IndexMut<usize, Output = Vector>,

Fills the block into a matrix at the given row and column offsets.

Provided Methods

fn block_size(&self) -> Option<usize>

The size of the independent square blocks along the diagonal that the block consists of, if that is what it is.

fn for_each_entry( &self, _function: &mut dyn FnMut(usize, usize, TensorRank0), ) -> bool

Calls the function with every entry the block holds explicitly, and says whether the block has any such notion.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
