Converting a symbolic expression into a numeric function
As we have seen the numerical evaluation of a symbolic expression is done in three steps, first we do some symbolic computations and then we substitute values by numbers and do an evaluation to a floating point number by evalf.
The reason for symbolic computations is often that one wants to make parameter studies. This requires that the parameter is modified within a given parameter range. This requires that an symbolic expression is eventually turned into a numeric function.
A study on the parameter dependency of polynomial coefficients
We demonstrate a symbolic/ numeric parameter study by an interpolation example to introduce the SymPy command lambdify. Let us consider the task to interpolate ...
