Class

Vector

An ordered, operable parser aggregate with heterogeneous ParserEntity elements.

remarks

Vector is not restricted to numeric linear-algebra values. General arithmetic is element-wise: scalar operands are broadcast across the Vector, while Vector operands are paired by position and must have the same length. Vector-to-Vector times remains an element-wise product rather than an alias for dot. A Matrix operand interprets this Vector as a row vector for the standard

`Vector * Matrix`

product; orientation is supplied by operand position rather than stored on the Vector. Structural methods such as append, insert, extend, reverse, and trim mutate this Vector. True linear-algebra operations (dot, cross, and norm) require Expression elements.

`dot`

requires equal lengths, while

`cross`

requires two three-element Vectors. These operations throw rather than assigning arithmetic meaning to arbitrary aggregate elements. Construction from a Collection copies its elements. Construction from an array normalizes inputs but retains existing parser entities; copy deep-copies every element. Comparisons are component-wise predicates, not a total ordering, and return false for a type or length mismatch.

Members

__get__(indices: number[]): ParserEntityMethod

throws

UnexpectedDataType If the index is out of bounds.

Parameters

Name	Type	Description
`indices`	`number[]`	Zero-based parser indices after index-base adjustment.

Returns

ParserEntity — The stored parser entity.

__set__(indices: number[], value: ParserEntity): voidMethod

Sets the element at the given index.

Parameters

Name	Type	Description
`indices`	`number[]`	A single-element array [i]
`value`	`ParserEntity`	The value to set

Returns

symbolicAccessor: Expression[]Property

Public index expressions retained when bracket access cannot yet be resolved. This state belongs to a copied structured entity, never the stored source value.

text(): stringMethod

No description is available yet.

Returns

string

times(x: NerdamerInput): VectorMethod

Multiplies corresponding Vector elements, broadcasts a scalar factor, or multiplies this Vector from the left of a Matrix.

remarks

Vector-to-Vector multiplication is the element-wise (Hadamard) product. Use dot when a scalar inner product is intended. For a Matrix operand, this Vector is interpreted as a row vector. Nonzero-width products reuse the existing Matrix-vector product through the transpose; a compatible zero-width Matrix has the empty Vector as its result because its transpose cannot be represented.

throws

DimensionError If Vector dimensions are incompatible.

throws

MathError If Matrix dimensions are incompatible.

Parameters

Name	Type	Description
`x`	`NerdamerInput`	—

Returns

Vector

Returns

string

trim(): VectorMethod

Removes every element equal to zero.

Returns

Vector — This mutated Vector.

withSymbolicAccessor(target: Expression, indices: Expression[]): VectorMethod
