MATLAB: Please help with this function

Question

function [th rad]=cartopolar25(x,y

t=atan(y/x); rad=sqrt(x^2+y^2); if if x<0 if y<0 th=180+t return else th=180-t return end else if y<0 th=-t return else th=t return end end

end end

Hi I need help with this code, if you guys see any mistakes please let me know. I have to make a function to determine the polar coordinates from the Cartesian plane, thanks for the help yes I was able to get the degrees now all I need is the radians any tips with this current format thanks

Answer 1

your function is this:

function [th rad]=cartopolar25(x,y)
th = atan(y/x);
rad = sqrt(x^2+y^2);
if x<0
    if y<0
        th=th+180;
    else
        th=th-180;
    end
else
    if y<0
        th=-th;
    end
end

and you need to call it like this:

[t,r] = cartopolar25(-11,20);

the output will be:

t =
      -181.0680
r =
     22.8254
