#toJSON

Returns the matrix in the same plain-object shape as toObject, for passing to JSON.stringify.

import { Matrix } from "@teakit/matrix";

Matrix.toJSON({ b: [1], a: [2] }); // { a: [2], b: [1] }  (keys ascending)

// Serialization follows native JSON rules: a row `undefined` becomes `null`.
JSON.stringify(Matrix.toJSON({ a: [1, undefined, 3] }));
// '{"a":[1,null,3]}'

• For a string, call JSON.stringify(Matrix.toJSON(matrix)); the package has no Matrix.toString / Matrix.valueOf.
• The returned shape matches toObject.
