Please how do i find the inverse kinematics for a 5 dof serial manipulator using matlab ikine()

Question

I am trying to find the inverse kinematics for a 5 DOF robot. These are my parameters.

L(1) = Link([0, 0, 0, pi/2]);
L(2) = Link([0, 0, 37.5, 0]);
L(3) = Link([0, 0, 37.5, 0]);
L(4) = Link([0, 0, 0, pi/2]);
L(5) = Link([0, 30, 0, 0]);`

`Robot.tool = transl(0,150,0)*trotx(pi/2);`

I am trying to find the inverse kinematics for this position
