tf2tex( tfobj, sstr, input, output)

Convert a transfer function to LaTeX math code

To speed up LaTeX reporting, this function converts a numerator and denominator array that is taken from a MATLAB tf object to LaTex math code. The LaTeX character for s (Laplace variable) can be specified (for example \gls{sym:s} if a symbols list is used). Furthermore it can handle MIMO tf objects, specifiying which input and output is of interest.
