Angle function output convention
显示 更早的评论
Why does the function 'angle(complex_input)' output values between +pi and -pi radians? Normal convention is 0 to 2*pi. I find this confusing. What am I misunderstanding? Is there a way to convert this? Simply adding pi to the output did not seem to work.

It is consistent with other computer languages for atan2, etc., so for consistency, I presume, TMW chose to keep it that way instead of being "odd man out".
To convert, add 2pi only for angle < 0

a = mod(angle(z),2*pi);
