Newton Raphson Method for 4 equations

syms x g h k l q a b c d f w

a = 0.1;

b = 0.15;

c = 0.25;

d = 0.3;

f = 0.2;

g = 135;

w = 20;

x = 0.236;

y1 = (x*cos(q)+x*cos(g)-f*cos(l)-(b/2)*cos(h)-a*cos(q));

y2 = (x*sin(q)+x*sin(g)-f*sin(l)-(b/2)*sin(h)-a*sin(q));

y3 = (a*cos(q)+b*cos(h)-c*cos(k)-d);

y4 = a*sin(q)+b*sin(h)-c*sin(k);

y = [y1; y2; y3; y4];

v = [x; (h); (k); (l)];

B = jacobian(y, q);

J = jacobian(y, v);

initial value : it does not matter

I want to find h, k, l value with newton raphson.

You cannot find those values with the information specified, as you do not have any equations indicating what "y" or B or J should equal. Without those equations to provide constraints, h, k, and l may be anything.
