Problem with eigen vectors matrix - help !!!

[liorwavebreak_tv]

I am using ippmEigenValuesVectorsSym_m_32f in order to calculate Evals and Evecs of matrix B

matrix B is the result of A*A' and it is symetric ..

now the problem:

When comparing to MATLAB results:

Matrix B is equale in both programs (matlab and c code)

the eigen vectors are NOT equale, how come ???

also tried to use ippmEigenValuesVectors_m_32f .. but no good.

and one more thing:

does ipp provides a solution for the general eigen problem ?

meaning :

input : matrix A, matrix B

A*V = B*V*D

output:

eigen vecs V

eigen vals D (diagonal matrix)

thanks,

is there a reason why no one reply to my questions ?
