How can I plot a transfer function with linear amplitude in MATLAB?

[mrachidi]

hello,
please i need ur help. i want to draw this transfer function m = tf ([1,0,1,0],[2,0,1]) in MATLAB and i want the y-axis to be the amplitude and x the frequencies. This is not Bode because i want the amplitude to be linear and not log scale. thank u for your help

You can change the bode plot options FreqScale and MagScale to 'linear'.

Alternatively you could use freqresp to produce the y values and then plot.
