Hi, I need to solve A*x=B for size(A)~[10,10,1e5] and size(B)~[10,1,1e5], and it seems like something like pagefun would be the way to do it: except that mldivide is not an option. I understand that cuBLAS has had the ability to run batch LU decompositions for some time and the newer cublas also seems to have a batched solver.
Is there a reasonably simple way to implement this in MATLAB (preferably R2013b or earlier)?
Thanks

Unfortunately, as you have found PAGEFUN does not yet support batched MLDIVIDE. You might be able to use the GPU Mex interface to call CUBLAS yourself.

Just chiming in: I also have a need for a pagefun 'mldivide'. If someone has done the MEX implementation already, please link. It would be greatly appreciated.
