Expand description

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)§

This enum is marked as 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.

ColumnBasis

Rectangular numerical column-basis selection.

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.

IntervalReciprocal

Outward-rounded interval reciprocal.

IntervalDivision

Outward-rounded interval division.

IntervalSolve

Interval Gaussian elimination and back substitution.

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.

VectorAngle

Unsigned angle between two vectors.
