[dependabot]

Bumps mathjs from 6.6.5 to 9.2.0.

Changelog

Sourced from mathjs's changelog.

2020-02-03, version 9.2.0

• Implemented function count to count the total elements in a matrix, see #2085. Thanks @Josef37.
• Fix #2096: cleanup old reference to external dependency crypto.
• Some refactoring in the code to remove duplications, see #2093. Thanks @Josef37.

2021-01-27, version 9.1.0

• Extended function reshape with support for a wildcard -1 to automatically calculate the remaining size, like reshape([1, 2, 3, 4, 5, 6], [-1, 2]) which will output [[0, 1], [2, 3], [4, 5]]. See #2075. Thanks @Josef37.
• Fix #2087: function simplify ignores second argument of log, for example in simplify('log(e, 9)') . Thanks @quentintruong.

2021-01-16, version 9.0.0

• Improved support for bin, hex, and oct literals. See #1996. Thanks @clnhlzmn.
  • Breaking change: parse literals with prefixes 0b, 0c, and 0x are
    now unsigned by default. To parse them as signed, you have to specify a suffix specifying the word size such as i16 or i32.
  • Function format now supports more notations: bin, 'hex', and oct, for example format(255, {notation: "hex"}).
  • The functions format, bin, hex, oct now allow specifying a wordSize, like bin(10, 32) and format(10, {notation: "bin", wordSize: 32}).
  • BigNumber support for the bin, hex, and oct literals.
• Extended and improved the example rocket_trajectory_optimization.html. Thanks @Josef37.

2020-12-30, version 8.1.1

• Improved the performance of parsing and evaluating units a lot, see #2065. Thanks @flaviut.
• Upgraded dependency fraction.js to v4.0.13.
• Moved continuous integration testing from Travis CI to Github Workflow, see #2024, #2041. Thanks @harrysarson.

2020-12-04, version 8.1.0

• Implemented units kilogramforce (kgf). Thanks @rnd-debug.
• Fix #2026: Implement a new option fractionsLimit for function simplify, defaulting to Infinity.
• Improved the documentation of function clone. Thanks @redbar0n.
