Math.js is an extensive math library for JavaScript and Node.js. It features a flexible expression parser with support for symbolic computation, comes with a large set of built-in functions and constants, and offers an integrated solution to work with dif

   * Transpose and complex conjugate a matrix. All values of the matrix are
   * reflected over its main diagonal and then the complex conjugate is
   * taken. This is equivalent to complex conjugation for scalars and
   * vectors.
   *
   * Syntax:
   *
   *     math.ctranspose(x)
   *
   * Examples:
   *
   *     const A = [[1, 2, 3], [4, 5, math.complex(6,7)]]
   *     math.ctranspose(A)               // returns [[1, 4], [2, 5], [3, {re:6,im:7}]]
   *
   * See also:
   *
   *     transpose, diag, inv, subset, squeeze
   *
   * @param {Array | Matrix} x  Matrix to be ctransposed
   * @return {Array | Matrix}   The ctransposed matrix
