MATLAB: How to change the conventional theta values from [-90,89] to [0,359]

Question

Hi with reference to the Hough lines, I would like to know how to use the theta values which are from [0,359] instead of the default one.

Answer 1

 lines = houghlines(BW, ...);
 shiftedTheta=num2cell([lines.theta]+180);
 [lines.theta]=deal(shiftedTheta{:});
