Hi! How to fix plane position as a 0 degree angle for Phi azimuth angle or how Matlab understand where Phi angle should be drawn?
A = 3.67 * sin(Phi0) * cos(Theta0); B = 3.67 * sin(Phi0) * sin(Theta0); C = 3.67 * cos(Phi0);

Unable to perform assignment because the size of the left side is 1 by 1 and the size of the right side is 1 by 2
You cannot do this - x=[1,2,3], x(1)=[5,6] %left side 1x1. right side 1x2
