Matra Math

Matra Math defines the math-domain layer built on the domain-neutral @matra/core AST. Its first stable boundary is conversion between Matra function syntax and recursive MathJSON.

import { parseMath } from "@matra/math"

parseMath("Add(1, Power(x, 2))")
// ["Add", 1, ["Power", "x", 2]]

The historical implementation remains in legacy/bmath as a migration reference. New code uses Core's MatraAST (tag, props, children) rather than the former private node shape (head, attributes, children).

Matra props are rejected during MathJSON conversion because silently dropping them would corrupt the expression. Formula(expr) is accepted as an optional document wrapper and is unwrapped at the MathJSON boundary.

Computation

Cortex Compute Engine integration is an optional workspace package:

import { evaluateMatra } from "@matra/math-compute-engine"

evaluateMatra("Add(1, 2, 3)") // 6

Keeping this adapter separate allows @matra/math to define syntax and data without requiring a particular symbolic computation implementation.
