Compressed kernel matrix trait

Required Methods§

Source

fn get(&self, i: usize, j: usize) -> Result<Float>

Get kernel value at position (i, j)

Source

fn get_block( &self, row_start: usize, row_end: usize, col_start: usize, col_end: usize, ) -> Result<Array2<Float>>

Get a block of kernel values

Source

fn dimensions(&self) -> (usize, usize)

Get matrix dimensions

Source

fn compression_ratio(&self) -> Float

Get compression ratio achieved

Source

fn approximation_error(&self) -> Float

Get approximation error

Source

fn memory_usage(&self) -> usize

Get memory usage in bytes

Dyn Compatibility§

This trait is dyn compatible.

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