I have two huge matrices $A$ and $B$. I am trying to find some iterative solvers like bcg
or lsqr
in Matlab.
I mean if my matrix $A$ is sparse and $n\times n$ and $B$ is a column vector of size $n\times 1$, I can use lsqr
and bcg
to solve the equation $Ax=B$.
Now suppose I need to solve $XD=C$, so I need to calculate $CD^{-1}$ where both $C$ and $D$ are huge matrices. If I use matlab's C/D
operation directly, it consumes lots of memory and crashes. Are there any iterative solvers for this operation instead of using the forward slash operator directly?
