tanh function

Discussion in 'MATLAB' started by Yin Chin Choo, Sep 3, 2007.

  1. Hi all,
    I wanted to plot a frequency domain plot using a transfer
    function. The transfer function involves a term tanh(Te*s)
    where Te is a time constant. However, function 'tanh' is
    not defined for values of class 'tf' in Matlab.

    How can I plot a frequency domain plot utilising a
    transfer function which involves a term tanh(Te*s)? Any
    suggestion will be appreciated.
