Y = atan(X)
Y = atanh(X)
atanhoperate element-wise on matrices. Their domains and ranges include complex values. All angles are in radians.
atan(X) returns the inverse tangent for each element of
X. For real elements of
X in the range [-1,1],
atan(x) is in the range [-
atan(X) is always real.
atanh(X) returns the inverse hyperbolic tangent for each element of
-2 <= x <= 2.
x = -2:.05:2;
