This MATLAB function returns the secant function of X. Secant Function for Numeric and Symbolic Arguments. Depending on its arguments, sec returns floating-point or exact symbolic results. Compute the secant function for these numbers.

Description. Y = sec (X) returns the secant of the elements of X. The sec function operates element-wise on arrays. The function accepts both real and complex inputs. For real values of X, sec (X) returns real values in the interval [-∞, -1] and [1, ∞]. For complex values of X , sec (X) returns complex values.
