Hi
I tried to use the ippmInvert_ma_32f_S2-Function for small matrices. I recognized, that the size of the buffer has to be larger than heightWidth^2. In my case the function works fine, if bufferSize = 1.5 * heightWidth^2 is used. I don't know if its a bug or the error on my side.
I'm using the IPP 4.0.
Thanks a lot
M.W.

Hello,
there is answer from our expert:
The IPP 4.0 documentation contained the bug which has been fixed since the version IPP 4.1.
The actual buffer size is (heightWidth^2+heightWidth).
I would like to advise using the last IPP versions for small matrices which provide better performance and reliability.
Note, the latest IPP version is v5.1
Regards,
Vladimir
