This is the documentation for the Python repository timescalecalculus.
The basics
After extracting the files, open a Python instance in its folder and type
>>> from timescalecalculus import *
Now the full functionality of timescalecalculus is available to you.
Defining a time scale
Right now, a time scale can consist of only a finite list of numbers. Fraction types are available.
>>> ts=[1,2,3,4,5,6,7]
The forward jump $\sigma$ can be used:
>>> sigma(3,ts) 4
The backward jump $\rho$ can be used:
>>> rho(3,ts) 2
The delta derivative works as expected. The delta derivative of a constant is zero:
>>> dderivative(lambda x: 1,5,ts) 0
and obeying the delta derivative of squaring function, we see
>>> dderivative(lambda x: x*x,5,ts) 11
