Simulink Reference | ![]() ![]() |
Display a transfer function on the icon of a masked subsystem.
Syntax
Description
dpoly(num, den)
displays the transfer function whose numerator is num
and denominator is den
.
poly(num, den, 'character')
allows you to specify the name of the transfer function's independent variable. The default is s
.
When the icon is drawn, the initialization commands are executed and the resulting equation is drawn on the icon:
You can add a fourth argument ('z'
or 'z-'
) to express the equation in terms of z or 1/z.
If the parameters are not defined or have no values when you create the icon, Simulink displays three question marks (? ? ?
) in the icon. When the parameter values are entered in the mask dialog box, Simulink evaluates the transfer function and displays the resulting equation in the icon.
