Arithmetic operation associated with a computation failure.

This identifies both non-finite intermediates/results through NonFiniteOrigin::Computation and finite-endpoint range exhaustion through LaError::IntervalRangeExhausted.

Examples

use la_stack::ArithmeticOperation;

assert_eq!(ArithmeticOperation::LuSolve.to_string(), "LU solve");

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

MatrixInfinityNorm

Matrix infinity-norm calculation.

SymmetryCheck

Matrix symmetry validation.

LuFactorization

LU factorization.

LdltFactorization

LDLT factorization.

LuSolve

Forward or backward substitution with an LU factorization.

LdltSolve

Forward, diagonal, or backward substitution with an LDLT factorization.

Determinant

Determinant calculation.

DeterminantErrorBound

Determinant error-bound calculation.

IntervalAddition

Outward-rounded interval addition.

IntervalSubtraction

Exact-real subtraction enclosed by an outward-rounded interval.

IntervalMultiplication

Outward-rounded interval multiplication.

IntervalSquare

Outward-rounded interval square.

IntervalDeterminant

Division-free interval determinant calculation.

VectorDotProduct

Vector dot-product calculation.

VectorDotDifference

axis · (left - right) without first rounding the vector difference.

VectorSquaredNorm

Vector squared-norm calculation.

VectorNorm

Overflow- and underflow-safe vector Euclidean-norm calculation.
