Then you did it wrong. What's your entire code now?
Do you really want to know?
The results of logic, of natural progression? Boring! An expected result? Dull! An obvious next step? Pfui! Where is the fun in that? A dream may soothe, but our nightmares make us run!

Hi

Well, actually putting the code I gave you in the function at all would probably help
I did. That was the first thing I tried. It was completely ignored by the compiler.

Then you did it wrong. Show me how you put it in.

Code: Select all

``````double dsigmoid(double x){
double e=2.71828;
double k=0;
if (x>700){
return 0;
}
double j=pow(e, x);
double l=j+1;
double h=pow(l,2);
k=j/h;
return k;
}``````
Here you go.

Make sure you're saving where you think you're saving, compiling the file(s) you think you're compiling, and running the executable you think you're running.

I'm using sublime text for speed. ST has a single button for saving, compiling, and running. 'Course, that's irrelevant now, because it's working for some reason. All I needed to do was hammer the compile button 12 times in a row without stopping to actually let it compile.

Thanks for the help guys.

I avoided using any of this capability assiduously for years, but in a matter of months I have been converted.

It started when I realized that I was getting really sick of (a) not having any programs that really worked well with emacs-type keybindings, and (b) also not being able to work efficiently with Python scripts (in particular) which I edited within emacs. In the meantime, because of the need to work remotely, I let someone show me how "cool" Jupyter is, for flexible Python scripting and prototyping, but I couldn't stand it for various reasons, all of which boiled down to it Not Being Emacs.

So I bit the bullet and looked for a way to integrate Jupyter Lab functionality into emacs. I found it and my remote productivity shot up. Not only could I use my beloved keybindings, but the integration also solved some crucial (and really idiotic) flaws that were otherwise present in Jupyter anyway, like not being able to copy-paste from a script to a notebook.

From there my fate was sealed.

I have just integrated LaTeX into emacs and can cycle my formatting like a madman. It's basically WYSIWYG at this point! (Don't talk to me about Overleaf.) It's only a matter of time before I look for C-prototyping, and SWIG C-integration with Python is a no-brainer. I wonder if I can run MacOS from within emacs...
