| Thanks Jose, I appreciate it. While this is very useful, the fact that I need to know the result before verifying it is a limiting factor. I think it would be great if the WL (Full)Simplify and Eliminate commands could be extended to transform... |
| ODE with a DiracDelta at the origin fails using NDSolve (solution steps down at x=0). sol = NDSolveValue[{y'[x] == DiracDelta[x] , y[0.5] == 0.}, y, {x, -1, 1}] Plot[sol[x], {x, -1, 1}] ![enter image description here][1] ... |
| This is beautiful -- exactly what I was looking for! Thank you. |
| Great! Still struggling to have Mathematica simplify matrix expressions though. See the very simple example below. How do I simplify A1.A2 + A1.A3 with A2+A3 == 0 to 0 (or a zero matrix)? How can I make Mathematica scour through a collection of... |
| yes, that was the intention, as it allowed me to test cff in a loop for many different arguments. The issue remains that FindMinimum and NMinimize appear to evaluate the objective function symbolically as implied by the error message During... |
| Thanks -- that worked! |
| Beautiful. Thank you! Yes, in the end I was able to make this work in my code, too. Thanks again. |
| The purpose of this post is to ask the Mathematica community to chime in on (i) how to best teach students concepts of Grad - Div - Curl using Mathematica, and (ii) how to optimally represent such fields for certain classes of functions using... |
