hi
i'm gonna design a controller by using sisotool but as I define a trasnfer function and try to open sisotool it shows me below error:
Error using controlSystemDesigner (line 245)
The model for "G" must be single input, single output.
Error in sisotool (line 88)
h = controlSystemDesigner(varargin{:});
even when I try to obtain a step response by using 'step' command it either doesn't work and shows me the same error as written above
whooooooooooooooooooooooooo can help me ??

Works for me.
Are you sure you have defined the correct transfer function?
Try the following:
z = tf('z',1) % discrete variable (with Ts = 1)
g = 0.024187*(z+.9672)/(z-1)/(z-0.9048)
zpk(g) % check TF
Now open sisotool or other controller design tool, say
C = pidtune(g,'pi')
