+   * Calculate the hyperbolic secant of a value,

+   *
+   * To avoid confusion with the matrix hyperbolic secant, this function does
+   * not apply to matrices.
+   *
+   * Syntax:
+   *
+   *    math.sech(x)
+   *
+   * Examples:
+   *
+   *    // sech(x) = 1/ cosh(x)
+   *    math.sech(0.5)       // returns 0.886818883970074
+   *    1 / math.cosh(0.5)   // returns 0.886818883970074
