I am working with a project to replace Matlab with Python, in a calculus course. Issue: Current versions of SymPy can not explictliy generate the Laplace transform of a derivative. This is no problem for Matlab. Let me provide an example. In Matlab code: syms s y(t) Y # 1st and 2nd derivative of y wrt t Dy=diff(y(t),t); D2y=diff(Dy,t); laplace(Dy) laplace(D2y)
# Matlab output:: ans = s*laplace(y(t), t, s) - y(0) ans = s^2*laplace(y(t), t, s) - s*y(0) - subs(diff(y(t), t), t, 0) This property is crucial when solving Initial Value Problems without Python's dsolve routine. I address this issue to SymPy developers. Hope that future SymPy versions will do these calculations. -- You received this message because you are subscribed to the Google Groups "sympy" group.
