You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: genslblockfkine.m
    path of file: ./repos/Robotics-Toolbox/rvctools/release10.3.1/robot/@CodeGenerator
    
    the code of the file until where you have to start completion: %CODEGENERATOR.GENSLBLOCKFKINE Generate Simulink block for forward kinematics
%
% cGen.genslblockfkine() generates a robot-specific Simulink block to compute
% forward kinematics.
%
% Notes::
% - Is called by CodeGenerator.genfkine if cGen has active flag genslblock.
% - The Simulink blocks are generated and stored in a robot specific block 
%   library cGen.slib in the directory cGen.basepath.
% - Blocks are created for intermediate transforms T0, T1 etc. as well.
