Dear,
Is it correct that the dsyev function call is about 6 times slower than Jacobi from numerical recipes (11.1)for 3x3matriches ?
Is it possible to use the dsyev call with two dimensional arrays?
All feedback is highly appreciated!
Thanks,
Bart

Hi Bart,

Intel MKL is high optimized for large matrix operation. 3x3 matrixes are very small matrix for Intel MKL. MKL are not high optimized for them
