Hi,
Is there a way to simplify the zeros and poles of a transfer function matrix, when the laplace s term is represented using symbolic math toolbox. Because of the numerical error, matlab does not simplify the transfer function matrix. Or is there a way that I'm unaware of?

Many thanks

For a numeric transfer function use minreal(sys). For a symbolic transfer function use simple() or simplify().

I hope this helps
