Info
My current research is a mix between pattern recognition and neuroimaging.The purpose is using machine learning and pattern recognition algorithms on functional magnetic resonance imaging data to decode brain states, and/or analyzing structural brain data. I am also interested in developing computer vision techniques to detect 2D and 3D objects, applying evolutionary algorithms, and developing/using permutation testing methods. Besides music, (soccer) video games, scientific research is my other favorite pastime.

Which contains:
1- Armitage’s Trend Test, usually used in genome-wide association studies (GWAS)
2- Finding SNP markers contingency tables
3- Fast generation of Zernike radial polynomials via q-recursion
4- Fast generation of pseudo Zernike radial polynomials via p-recursion
5- Kintner's method to generate Zernike radial polynomials
6- Prata's method to generate Zernike radial polynomials
7- 2D, 3D, ND Trapezoidal integrals
Matlab versus C/C++ language, which one is faster?
To test for the speed issue, and how fast each environment is, I computed the so called pseudo Zernike radial polynomials for 1 milion r values, up to the order 99, using an efficient method widely known as the p-recursive.
Running the C++ executable in release mode:
[alrawi@srv Release]$Pzmp
Number of r values is: 1000,000 (1M)
execution time (s) of Pseudo Zernike Polynomials values is: 3.25 seconds
[alrawi@srv Release]$
As for matlab, the execution for the same size problem, by using vectorized technique, was nearly twice as that of the C function.
>> tic; R = pseudo_zernike_polynomials_p_recursive(99,0, x); toc
Elapsed time is 6.589477 seconds.
Result: For the above task, C is twice faster than matlab.
