Hi im having problem with Inverse kinematic using RVC toolbox in matlab for RRR manipulator.

L_1 = 20; L_2 = 50; L_3 = 40; L(1) = Link([0 L_1 0 pi/2]); L(2) = Link([0 0 L_2 0]); L(3) = Link([0 0 L_3 0]); Robot = SerialLink(L); Robot.name = 'RRR_Robot'; T = [1 0 0 0; 0 1 0 0; 0 0 1 0; 0 0 0 1]; J = Robot.ikine(T, [0,0,0], [1 1 1 0 0 0]) *180/pi;

Error using SerialLink/ikine (line 164) Number of robot DOF must be >= the same number of 1s in the mask matrix

Can somone explain me why my code is not working? / how to fix it ?
