I am doing some image processing involving solving a system of linear equations. I am getting some errors and bits of the image looks corrupted. I would like to know what is the most stable way to solve these systems (I don't care how much cpu it takes to compute). It should try to avoid roundoff, catastrophic cancellation, etc.What would be the most robust algorithm for this?
Most stable algorithm to solve a system of linear equations?
