In solving equation using 'solve', I tried to change the constant part by a small value say 0.1. But, If I change the value by 0.1 the solution is completely different and far away from the exact solution. Is there any solution?
syms x y z a = (sqrt((x-SatPos(1,1))^2+(y-SatPos(1,2))^2+(z-SatPos(1,3))^2)==Dis(1)); b = (sqrt((x-SatPos(2,1))^2+(y-Sat...
