I really enjoy working with the control system functionality in Mathematica. My thanks and congratulations to the developers! I Would like to respectfully request two enhancements to the plotting capability: 1. I would like to see tooltips...
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],...
For years, Wolfram has claimed that Mathematica supports import and export from all major CAD formats. But, in fact, it has not supported STEP, IGES, or SAT, which are the CAD formats primarily used in mechanical engineering. I just finished...
1. A little note that one must first, of course, save the current notebook before setting the `SetDirectory`. 3. This method is not as general as one might wish, since the `.mx` file is saved in the current notebook's directory and not in...
Any update on this? The numebr of exchanges listed is still very poor...
Hi, David, THANKS A LOT for the kind assistance ! As soon as I come back from vacation at sea, I will put in operation your notebook, but I have no doubt that you solved my problem. :-) I will post again in case I will make some additional...
Hello, in case anyone still needs assistance, this link may help: https://mathworld.wolfram.com/EulerEquation.html .
Example: p = {a, I b}; q = {c, I d}; In[3]:= p . q Out[3]= a c - b d Another: z = {I 3, I 4}; u = {I 5, I 6}; In[6]:= z . u Out[6]= -39
It would seem to me that bw bars produce an effect similar to a strobe light.
Hi Etienne, thank you for the book. I did learn a lot about neural Networks with Mathematica. Most of the code is running perfectly - it's really fun. Only a few lines and examples are not working. For example I can not get the decoder of the...
