Error types related to matrix inversion

Variants

NotSquare

The input or output matrix is not square

Fields

rows: i32

cols: i32

BackendError(i32)

Backend returned a non-zero error code

Singular

Matrix is singular: U(i,i) is exactly zero

Fields

pivot: i32

NotPositiveDefinite

The leading principal minor is not positive (Cholesky decomp)

Fields

lpm: i32

Trait Implementations

impl Debug for InvError

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

Formats the value using the given formatter.

impl Display for InvError

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

Formats the value using the given formatter.

impl Error for InvError

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.
