I have had very little instruction in MATLAB and my university is expecting me to preform what for me seem like very complicated tasks in MATLAB.
I have a z domain transfer function similar to,
H(z) = 0.03+0.52z^-1+0.71z^-2+0.52z^-3+0.03z^-4
which describes the frequency response of a filter. I am supposed to compare the shape of the filter to a quantized version. Quantization is the easy part but I cant figure out how to graph the transfer function. In fact I cant even figure out how to enter the transfer function into MATLAB. Everything I have tried results in

Error: Unexpected MATLAB expression.
Can someone help me with this please?
