Secant of angle in radians
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 in the interval [-Inf, Inf], sec returns real values in the interval [-Inf ,-1] and [1,Inf]. For complex values of X, sec returns complex values. All angles are in radians.
Plot the secant over the domain and .
x1 = -pi/2+0.01:0.01:pi/2-0.01; x2 = pi/2+0.01:0.01:(3*pi/2)-0.01; plot(x1,sec(x1),x2,sec(x2)), grid on
Calculate the secant of the complex angles in vector x.
x = [-i pi+i*pi/2 -1+i*4]; y = sec(x)
y = 0.6481 + 0.0000i -0.3985 + 0.0000i 0.0198 - 0.0308i
Input angle in radians, specified as a real-valued or complex-valued scalar value, vector, matrix or N-D array. The sec operation is element-wise when X is non-scalar.
