https://community.intel.com/t5/Intel-Integrated-Performance/Complex-numbers-in-matricies/m-p/874155#M9305 <BR />Hi all, <BR /><BR />I am currently using the IPP for matrix maths. This IPP library contains functions that I can use to transpose matricies, multipy them, etc. The element of each matrix is of data type Ipp32f. All this is fine. I can make matricies of real numbers and manipulate them beautifully. <BR /><BR />The problem however, is how do I make matricies of COMPLEX numbers using IPP???? <BR /><BR />This is driving me nuts. <BR /><BR />Thank you!<BR /><BR /> Wed, 09 Sep 2009 17:34:34 GMT mrmatrix 2009-09-09T17:34:34Z https://community.intel.com/t5/Intel-Integrated-Performance/Complex-numbers-in-matricies/m-p/874155#M9305 <BR />Hi all, <BR /><BR />I am currently using the IPP for matrix maths.

I would recommend yo to use Intel MKL for complex matrix operations.<BR /><BR />Regards,<BR /> Vladimir Thu, 10 Sep 2009 22:13:32 GMT https://community.intel.com/t5/Intel-Integrated-Performance/Complex-numbers-in-matricies/m-p/874156#M9306 Vladimir_Dudnik 2009-09-10T22:13:32Z https://community.intel.com/t5/Intel-Integrated-Performance/Complex-numbers-in-matricies/m-p/874157#M9307 <DIV style="margin:0px;"> <DIV id="quote_reply" style="margin-top: 5px; width: 100%;"> <DIV style="margin-left:2px;margin-right:2px;">Quoting - <A href="https://community.intel.com/en-us/profile/336498">Vladimir Dudnik (Intel)</A></DIV> <DIV style="background-color:#E5E5E5; padding:5px;border: 1px; border-style: inset;margin-left:2px;margin-right:2px;"><EM><BR />Hello,<BR /><BR />IPP small matrix domain is mostly targeted for media and 3D gaming math areas where complex arithmetic is not required.
