I am using 'lcapy' library in python to calculate inverse Z transform of a given function H(z). The problem is that h(n) output of 'IZT()' looks like a symbolic output for display, and I cannot plot or process it as a typical array or number in python.
One example is when I want to plot h(n) only for a limited numbers of n s, I receive the following error: TypeError: float() argument must be a string or a number, not 'DiscreteTimeDomainExpression'
That would be great if anyone guide me how I can convert the output of h=H.IZT() into a typical number for n=1, for instance. Many thanks for any helps in advance.
