1- To convert polar to cartisian coordinates, I use "Pol2Car(R,theta). Unlike any other matlab statment, I am surprised to note that the command works correctly only if the angle is in degrees rather than radians . It gives wrong answer if I use the angle in radians.
2 -The revers command Cart2Pol, output the angle in radians.
3- I checked the help and documintations of matlab 6.5, matlab 2010, and matlab 2015 for help on Pol2Car but couldn't find any.
