Eigen4AutoIt Features:
free, fast matrix computing environment for Windows (runs under Wine on Linux and Mac) built upon the robust Eigen code base (open-source), with many enhancements simple, intuitive functions, with extensive online documentation supports integer, single, and double precision, in real and complex matrices Tutorials with scripts, plus Test scripts for each function section easily exchange data between native binary files (.mat) and ASCII, Excel, and Xbase files, or AutoIt arrays 32-bit (x86-mode) and 64-bit (x64-mode) support in x64-mode, matrices can be any size that fits into available virtual memory (>4GB), and can be shared between processes over one thousand alias wrappers for flexibility and ease-of-use
The Eigen4AutoIt thread is here:
This computing environment allows you to do matrix I/O (memory & files), matrix arithmetic, transformation, reduction, and decomposition, solve systems of linear equations, and perform statistics. Most functions can act on integer, real, or complex matrices (or the latter's real/imaginary parts separately). Much of the actual complexity of using Eigen in its native C++ environment has been hidden for AutoIt users, through extensive bounds and error checks, an intuitive function-naming convention, a large help file, and detailed tutorials and test examples.

Hello friends! I have been working on an encryption algorithm in autoit as a proof of concept for some time now. Basically the algorithm uses a progressive recursion to encode data inside a matrix using a key that changes according to the date-time of the system, which is extracted from a larger key array. Recently after a drive failure, I lost the source and had to start from scratch, now I can't quite get it working the way it was before, and I can't see what I'm doing wrong, if anyone who understands matrix math or encryption could help I would much appreciate it. The problem is that the values returned by the decryption (extraction) process are way too big.
I have figured out the solution to my problem, it was a typo, please disregard this thread.
I will post my project into example scripts when it's ready.

i searched the forum, but didn't find anything.
has anyone an idea or ever done it with autoit ? simple image transforming, like sharpness, brightness, blurring etc. ?
maybe, does gdiplus.dll feature that ?
here is a tutorial on how to do it the hard (mathematical) way. http://lodev.org/cgtutor/filtering.html before i try that, i wanted to know if there is already an existing project or an idea or anyone has experiences.
thx

Hi there!
I have been learning linear algebra in my university for months. The subject was rather hard, I did't understand it much so I sent a email to my teacher to ask him. But I realized that typing a matrix by text was extremely hard. I don't want to make a LaTex function, save to a file, attach it to the mail, bla bla bla!!! It's complicated! So I spent 2 hours yesterday to make this tool. Just type the number of lines and columns and matrix values, it will generate a quite nice matrix in ASCII characters
Enjoy!
Notes: It will rearrage your numbers to straight columns.
1x1 will cause error.
