I tried to solve this system of ecuation but somenthing it´s wrong :

this is the code:

Ay=1

Az=-2

By=2

Bz=-1

r=1

x = optimvar('x',2);

ec1=((x(1)-Ay)^2+(x(2)-Az)^2)==r^2;

ec2=((x(1)-(Ay))^2+(x(2)-(Az))^2)==((x(1)-((By))^2+(x(2)-(Bz))^2));

prob = eqnproblem;

prob.Equations.ec1 = ec1;

prob.Equations.ec2 = ec2;

show(prob)

x0.x = [1 -2];

[sol,fval,exitflag] = solve(prob,x0)

disp(sol.x)

Do you have Optimization Toolbox™ installed? Check by running the ver command. You might need to install or reinstall.
