Write a function that will convert the reference angle returned from the Matlab atan(x) function to a positive angle as measured from the positive x-axis. The output angle should be in the range from 0 to 360 degrees. The header definition line for your new function is: function [angle_in_degrees] = arctan(x - coord, y-coord) This function requires you to determine which quadrant the coordinate pair is located so you can convert the reference angle to an angle measured from the positive x-axis
