Way to invert a₀I + a₁J #260

Open rveltz opened 4 years ago

rveltz commented 4 years ago

Hi,

I am wondering if there is a simple way to solve (a₀I + a₁J) x = rhs using gmres and J like gmres(J, rhs, a₀, a₁). KrylovKit provides this option and this is very convenient.

Thank you for your help,

Best
