+   * Test element wise whether two matrices are equal.

+   * Examples:
+   *
+   *    math.deepEqual(2, 4)   // returns false
+   *
+   *    a = [2, 5, 1]
+   *    b = [2, 7, 1]
+   *
+   *    math.deepEqual(a, b)   // returns false
+   *    math.equal(a, b)       // returns [true, false, true]
+   *
+   * See also:
+   *
+   *    equal, unequal
+   *
+   * @param  {number | BigNumber | Fraction | Complex | Unit | Array | Matrix} x First matrix to compare
+   * @param  {number | BigNumber | Fraction | Complex | Unit | Array | Matrix} y Second matrix to compare
+   * @return {number | BigNumber | Fraction | Complex | Unit | Array | Matrix}
+   *            Returns true when the input matrices have the same size and each of their elements is equal.
