Hello,

I'm seeing two different sizes listed for the "tmp" array supplied to DFGMRES:

((2*ipar(15)+1)*n+ipar(15)*ipar(15)+9)/2 + 1) from here, and

((2*ipar(15)+1)*n+ipar(15)*(ipar(15)+9)/2 + 1)) from here.

What is the correct size of "tmp"?

Thanks,
Greg

Hi Greg,
In the first variant number of left brackets is not equal to number of right brackets so only the second variant could be correct :)
With best regards,
