r3.*cos(th3guess),r4.*cos(th4guess),0,0;...
0,0,-r5guess.*sin(th5guess),cos(th5guess);...
0,0,r5guess.*cos(th5guess),sin(th5guess)];
dth = J\f;
th3guess = th3guess+dth(1);
th4guess = th4guess+dth(2);
th5guess = th5guess+dth(3);

f = [-(r2 + r3.*cos(th3guess) - r4.*cos(th4guess));...
-(0 + r3.*sin(th3guess) - r4.*sin(th4guess));...
-(0 + r5guess.cos(th5guess) - 0);... %<== error occurs here
-(0 + r5guess.sin(th5guess) - 0)];

r5guess.*cos(th5guess)
r5guess.*sin(th5guess)
instead of
r5guess.cos(th5guess)
r5guess.sin(th5guess)
