| I'm not sure where I got the idea that: ClearAll["Global*`"] should work but somehow I did get that idea: What works: ClearAll["Global`*"] |
| Examples for: **Functional(Delay ) Integro-Differential Equations Involving Caputo Fractional Derivative with initial conditions or boundary conditions .** NDSolve[{CaputoD[y[x], {x, 1/2}] - 3 y[x - 1] + Integrate[y[2 t],... |
| Try this. https://arxiv.org/abs/2109.04193 OGRe: An Object-Oriented General Relativity Package for Mathematica |
| If you want to have the result in the form for input to Mathematica functions that expect points to be lists of coordinates, you'd have to do an additional conversion. Not sure if I'm doing this correctly, but something like this is needed. Here,... |
| You might want to use `MatrixLog` instead of `Log`. |
| Hey Jos, thanks for your suggestion. I will try this out... |
| For the intended application, it does not matter. What is important is that `g1` and `g2` are isomorphic if and only if `CanonicalGraph[g1] === CanonicalGraph[g2]`. There are many different ways to define (and compute) a canonical form with this... |
| "I had placed the assumptions inside the Integrate command [ ] and ..." Which raises the question: Why was this code not indicated in the original post? If you do not provide actual code then (i) Nobody can diagnose for possible mistakes and (ii)... |
| Actually, they have a feature for this now - it's "PlusMinus[x]"! - Say you want "y = 2x ± 5" - put in "y = 2x PlusMinus[5]"! - If you want "y = 2x ±(5+7+9)" - put in "y = 2x PlusMinus[5+7+9]"! |
| And if you want it to a certain number of digits, you can use something like 1`20 Pi |
