Math Library - algebra, trigonometry, distributions, etc. 49 functions to solve all kinds of math problems.

Download source files - 39 Kb

In...

I created this library in 2001. Back then, I really needed a couple of math routines to work with series... after a couple of weeks, I finishing this. Maybe finish is not the right term, because I never got to properly test all of it.

In this library, you will find a lot of algebra, trigonometry, distributions, differentials, integrals and more. To use all these routines, just include hmathematica\hmathematica.h and add the generated hmathematica.lib into your project.

...and Out!

Not many of you need something like this... only if you work at some NASA-like places, but in this case you probably are some genius and don't need this.

Why a so poor article ?

I don't really understand the reasons for a so poorly documented article.
OK: about math there's few thing to say: if someone doesn't know certain concept, may be the case to read a math book, not an article.

But about coding...
I gave a look to the code. I don't really understand the need for a MFC project for a thing that is nothing more then a collection of headers where all functions are inlined. The only cpp file contains nothing more than an empty CWinApp.

Also, all header contains the function definitions, but no "inline" directive is present. In this case, if a same header goes to be included in more than a single translation unit (cpp file) of a same executable(in a NASA-like app, that's common Smile | :)

Smile | :)

) the linker will find multiple symbols, issuing liker errors.

In other words:

what are the reasons for an MFC DLL for this kind of libraries ?
why not a static library or even a pure "inline" library ?
Is there any particular reason to have only "functions" and not "classes" th handle interrelated elements?
why not using namespaces or other language features '

Any of this point may have different anwars that can be good or bad depending on the cases. In any of those cases your code require to be "restructured" to fit the needs, but you specifically prohibited it.

Moral:
5 for the math
3 for code engineering
1 for the article.

Hello,

Sorry for the delay.

I've made it mfc, because back than i probably considered that is the fastest way to do it. I've posted this article not to use it like it is... because it's not tested and it will not be updated... it's for those who really need to compute a more complex calculation and don't know how to implement it. So, they will probably take the code, not the .lib, and take what they need form there. That's why I didn't placed any binaries.

I'm sorry if you wanted to use it and had problems compiling it. Most likely I will never update this article - no time.

Thank you,

Then why on earth did you post such a half assed job of it? The whole point of posting these things is not to just dump a random collection of code but to actually write some sort article *plus* source code. Your topic could have been really interesting, I know that why I clicked on it, and I was really disapointed at the complete lack of effort in it.

How can I conjugate that disclaymer with your above post, in particular:

It seems you approve by default, but why put such a disclaimer ...
I'm still much more convicing that disclaimer are just ... bullshits!
