`scipy.special.``mathieu_cem`(m, q, x) = <ufunc 'mathieu_cem'>

  Even Mathieu function and its derivative

  Returns the even Mathieu function, `ce_m(x,q)`, of order m and parameter q evaluated at x (given in degrees). Also returns the derivative with respect to x of ce_m(x,q)

  Parameters: | m Order of the function q Parameter of the function x Argument of the function, given in degrees, not radians
  Returns: | y Value of the function yp Value of the derivative vs x
