https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/matrix-storage-order/m-p/905298#M11584 Hi,<BR /><BR />I'm calling MKL functions from C++.<BR />I would know how the functions store results in the matrixes. In the documents it says that is column major (but seems that is something wrong or not corrected).<BR />For example, in the case of 3x3 matrix in input, when I call <FONT face="Courier New">ztrevc </FONT>to find eigenvectors, I get in output vl (and vr). I want to know if <FONT face="Courier New">vr[0], vr[1] and vr[2]</FONT> is the first vector (or the first column of the vectors' matrix) or <FONT face="Courier New">vr[0], vr[3], vr[6]</FONT> is the correct form.<BR />Thank you.
