How can I use cart2pol?

Hello

cart2pol returns angles between -pi and pi, what I can do to have angles between 0 and 2*pi (0 and 360). thanks

mod(theta, 2*pi)

See also the unwrap() function.

Thak you sir

These lines

[ang,rho] = cart2pol(x,y);
ang = ((ang/(2*pi)) * 360);%convert to degrees orientation

give me this result

ang =

 -117.6064
 -117.7249
 -117.8443

when I add this line

ang=mod(ang, 2*pi)

I have this result

ang =

    1.7741
    1.6556
    1.5362

It's not correct?

The mod() is to be applied to the angle in radians, which is what you had asked about. Convert to degrees after you do the mod()
