You might want to make your code look a little nicer.

I don't mean any offence, but your code isn't the easiest to read. Perhaps go it over and write it in a clean way.

Sincerely

No offense taken.

Do you think if I make it more readable it will really make a difference to people? What's the use case?

Also, what do you mean by readable? Formatting? Or would you also like to see the math broken down into more descreet functions, so it's more obvious what's going on?

If you make a really good case, I'm open to it.

I like to look over code and essentially reuse code that might be helpful to me, and I'm glad to say that your code did work for my case, but it needed a lot of restructuring in order to make it compatible with my needs.

In most cases the math is quite easy to follow, I just believe that sometimes a lack of whitespace makes reading over code very difficult, especially when there are a lot of statements in small proximity, like for example, your for loop: for(i=0; i< res; i+=1){...}. As you can see (hopefully) the code is very cluttered and spacing is inconsistent. simply run it through Beautify and that would adress the issue.

Like I said, I don't mean any offence, I'm just trying to make it easier for people to read and understand your code.

If you already did this, feel free to make a PR.

[J-Cake]

Okay. I will do that.

If all the demo output still looks the same, I'll merge your changes in.
