+   * Squeeze a matrix, remove inner and outer singleton dimensions from a matrix.
+   *
+   * Syntax:
+   *
+   *     math.squeeze(x)
+   *
+   * Examples:
+   *
+   *     math.squeeze([3])           // returns 3
+   *     math.squeeze([[3]])         // returns 3
+   *
+   *     const A = math.zeros(3, 1)    // returns [[0], [0], [0]] (size 3x1)
+   *     math.squeeze(A)             // returns [0, 0, 0] (size 3)
+   *
+   *     const B = math.zeros(1, 3)    // returns [[0, 0, 0]] (size 1x3)
+   *     math.squeeze(B)             // returns [0, 0, 0] (size 3)
+   *
+   *     // only inner and outer dimensions are removed
+   *     const C = math.zeros(2, 1, 3) // returns [[[0, 0, 0]], [[0, 0, 0]]] (size 2x1x3)
+   *     math.squeeze(C)             // returns [[[0, 0, 0]], [[0, 0, 0]]] (size 2x1x3)
+   *
+   * See also:
+   *
+   *     subset
+   *
+   * @param {Matrix | Array} x      Matrix to be squeezed
+   * @return {Matrix | Array} Squeezed matrix
