Struct treerite::DMatrix

pub struct DMatrix<F> { /* fields omitted */ }

Data matrix used in Treerite.

Implementations

impl<F> DMatrix<F> where
    F: Float + FloatInfo, 

pub fn from_2darray<'a, A>(array: A) -> Result<DMatrix<F>, TreeRiteError> where
    A: AsArray<'a, F, Ix2>,
    F: 'a, 

Create a DMatrix from any type that can be converted to a 2d ndarray::ArrayView. This function is zero copy.

pub fn from_slice<'a>(array: &'a [F]) -> Result<DMatrix<F>, TreeRiteError>

Create a single row DMatrix from a slice of floats. Useful for prediction for a single instance. This function is zero copy.

pub fn from_csr_format<'a>(
    headers: &'a [u64],
    indices: &'a [u32],
    data: &'a [F],
    num_row: u64,
    num_col: u64
) -> Result<DMatrix<F>, TreeRiteError>

Create a csr format DMatrix. This function is zero copy.

impl<F> DMatrix<F>

pub fn nrows(&self) -> Result<u64, TreeRiteError>

Number of rows in this DMatrix

pub fn ncols(&self) -> Result<u64, TreeRiteError>

Number of columns in this DMatrix

Trait Implementations

impl<F> Drop for DMatrix<F>

fn drop(&mut self)

Executes the destructor for this type.

impl<'a, F: Float + FloatInfo> TryInto<DMatrix<F>> for &'a [F]

type Error = TreeRiteError

The type returned in the event of a conversion error.

fn try_into(self) -> Result<DMatrix<F>, Self::Error>

Performs the conversion.
