Diagonal close zero using PARDISO and mtype= 2

214 Views

Hi!,

I have a real, simmetric define positive matrix (mtype= 2) and I am factorizing using la function "pardiso". 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?.

Thanks,
