circle coordinates matlab

Plot line in polar coordinates - MATLAB polarplot ... At first polar coordinates seems like a great idea, and the naive solution is to pick a radius r uniformly distributed in [0, R], and then an angle theta uniformly distributed in [0, 2pi]. There are arguments in the squared parts, meaning there are horizontal and vertical shifts. Intersection points for pairs of small circles - MATLAB ... [lat,lon] = scxsc(lat1,lon1,range1,lat2,lon2,range2) returns in lat and lon the locations where pairs of small circles intersect. x and y are coordinates for the center of the circle. % (1) Select the a == angle of attack alpha a = -3; % in degrees a = a*pi/180; % Conversion to radians % (2) Select the parameter related to . theta=linspace (0,2*pi,200)%you can increase this if this isn't enough yet.
