Individual Links can be configured using the class Link of the Robotics Toolbox. Five parameters have to be set as a vector. The first four are \theta, d, a and \alpha and the last one defines the type of the joint. For a revolute joint, the type parameter has to be set to 0, for a prismatic joint to 1.

L = Link([theta d a alpha type])

So if a manipulator consisting of one prismatic joint and two revolute joints is to be created, the three links could be configured as follows:

The corresponding serial link is then created using the class SerialLink and passing the existing links in form of a vector as parameter:
