Tue 15 Oct 2019 12:34:39 AM UTC, comment #6: I cleaned up the patch and added a seealso link to cart2pol and checked it in here https://hg.savannah.gnu.org/hgweb/octave/rev/eeb2275424bc. Thanks for the patch. Marking as fixed and closing report.	Rik <rik5>

Sun 13 Oct 2019 10:29:37 PM UTC, comment #1: See the documentation from Matlab (https://www.mathworks.com/help/matlab/ref/polar.html). This is the expected result, input in radians with labeling in degrees. Can you prepare a patch for the documentation to mention that the input is in radians?	Rik <rik5>
Sun 13 Oct 2019 06:36:57 PM UTC, original submission: When using the polar command to plot, it draws an axis with 0 - 360 deg shown. The documentation also uses degrees. But it is assuming that the input data is in radians. q=rand(1,100); c=ones(1,numel(q))*2; # a vector of 2s polar(c,q,'.') This should draw a line at 2 degrees but it is a 2 radians. We can change the documentation or the calculations.	Doug Stewart <dastew>
