Enum DecompositionError 

pub enum DecompositionError {
    ShapeError(String),
    ConvergenceFailure {
        iterations: usize,
        residual: f64,
    },
    SingularMatrix,

    },
    EmptyTensor,
    NonMatrixInput {
        ndim: usize,
    },
}

Errors that can arise during tensor decomposition.

Variants

ShapeError(String)

Input shape is incompatible with the requested operation.

ConvergenceFailure

Iterative algorithm did not converge within the allowed iterations.

Fields

iterations: usize

residual: f64

SingularMatrix

A matrix is numerically singular and cannot be inverted.

InvalidRank

Requested rank exceeds the maximum feasible rank for the dimension.

Fields

rank: usize

max_rank: usize

EmptyTensor

Operation applied to an empty tensor (at least one dim is 0).

NonMatrixInput

Operation requires a matrix (2-D array) but received an n-D tensor.

Fields

ndim: usize

Trait Implementations

impl Clone for DecompositionError

fn clone(&self) -> DecompositionError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DecompositionError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for DecompositionError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for DecompositionError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
