eigen vectors and values algorithm

i need to know the algorithm by which matlab (or generally how can i) calculate the eigen values and vectors of a Non Symmetric matrix , i need the numeric algorithm to try to implement it in C

Matlab uses BLAS and LAPACK.

http://www.physics.orst.edu/~rubin/nacphy/lapack/eigen.html

If you want to know the actual implementation, then you should ask the Mathworks. They might not be so forthcoming in exposing the guts of Matlab though...

Note that both BLAS and LAPACK can be linked in a C program, so you'd just be reinventing the wheel.

please i'm not trying to reinvent anything here i'm trying to take this task as a tutorial for a self study on C programming

i need to know how to diagonalize a non symmetric matrix to get eigen vectors and values

please i need an algorithm to follow

Both BLAS and LAPACK are open source and one google search away.
