When it gives an error = -4 it because de diagonal value is negative o zero. Hower if the values is close to zero, it doesn't give any error. Is it possible to control when the diagonal value is close to zero and positive?.</P><P>&nbsp;</P><P>Thanks,</P> Mon, 01 Jan 2024 20:38:41 GMT Javi_Dopazo 2024-01-01T20:38:41Z https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/Diagonal-close-zero-using-PARDISO-and-mtype-2/m-p/1558928#M35688 <P>Hi!,</P><P>&nbsp;</P><P>I have a real, simmetric define positive matrix (<SPAN>mtype</SPAN>= 2) and I am factorizing using la function "pardiso".
