2023-10-26, 12.0.0

Breaking changes:

• Fix #2879, #2927, #3014: change the confusing interface of eigs (#3037), thanks @gwhitney. Before, functions eigs returned an object:

  { values: MathCollection; vectors: MathCollection }
  

  where vectors was a 2d matrix of which the columns contained the vectors. This is changed to eigs returning an object:

  { 
    values: MathCollection
    eigenvectors: Array<{
      value: number | BigNumber
      vector: MathCollection
    }>
  }
  

  Where eigenvectors is an array containing an object with the corresponding eigenvalue and vector.

• Refactored the TypeScript type definitions to make them work with a NodeNext module resolution (#3079, #2919).

  • Type MathJsStatic is renamed to MathJsInstance.
  • Type FactoryDependencies is deprecated, use MathJsFactory instead, and import dependency maps directly from the library.

• Change the assignment operator of .toTex() output from := to = (see #2980, #2987).

• Drop official support for Node.js 14 and 16.

Features:

• Function eigs now has an option to turn off calculation of eigenvectors (#3057, #2180). Thanks @gwhitney.

Fixes:

• Find eigenvectors of defective matrices (#3037). Thanks @gwhitney.

• Fix #3073: function format not escaping control characters and double quotes (#3082).
• Fix: function clone not throwing an error when passing an unsupported type like a function.
• Fix: #2960 add type definition of function symbolicEqual (#3035), thanks @juancodeaudio.

2023-10-11, 11.11.2
