I would like to use ippmQRDecomp_m_32f() function in IPP. I hope to find some examples using matrix operations. I don't see many examples in the manual (vol 3). If anyone knows where I can find more samples, please let me know. My question is quite simple, for a given matrix, find its Q, R matrices. I am comfused by the pointer to the matrix and strides.

I also wonder how to use the function: QRBackSubst(), since it needs two input arrays. But since QRDecomp() does not return two matrices (Q, R), what I need to do?

Hi,
did you try the latest version of IPP, v5.0 beta? We significantly change interfaces for matrix functions. The reason was to simplificate the usage and make it more consistent.
You can enroll to IPP v5.0 beta program here
Regards,
Vladimir
