angle

Phase angle

angle(A)

  • It returns the phase angle of each element of the array A.
  • The phase anges are in radians, with values between -pi and pi.
  • If A is empty, it returns an empty matrix.

Example 1: Plotting phase angles for various complex numbers.

x=-100:100;
[X,Y]=meshgrid(x);
Z=angle(complex(X,Y));
surf(X,Y,Z)
xlabel('x');
ylabel('y');
zlabel('angle(complex(x,y))')
Surface plot is generated.
