function F = Emissionangle(x) R_t = 1.4; R_mic = 1.6; U = 20 M = U/340 a_o = 340; a_t = 340; theta_mic=135 F = [ atand(sin(x(2))/(cosd(x(2))-M))-x(1); R_mic*cosd(theta_mic) - (R_t/tand(x(1)))-(( R_mic*sind(theta_mic)-R_t)/tand(x(3))); M - (1/cosd(x(2))) + (a_o/(a_t*cosd(x(3))))] xo =[ 135,135,135]. fsolve(@Emissionangle,xo)

I am not sure about the initial guess solution. I dont get a converged solution. Any help
