Sympy numerical evaluation

WebMost “symbolic” modules in SymPy take at least some advantage of numerical computing. SymPy uses the mpmath library for this purpose. Let’s start from something simple and find numerical approximation to π . Normally SymPy represents π as a symbolic entity: >>> pi π >>> type(_) . WebFeb 21, 2024 · But yes, it doesn't look like SymPy can integrate the product of a Bessel function with exp(-x**2) * exp(pi*I*(-x)). This happens already with r replaced by 1, so the …
