I started to learn numerical liner algebra on my own and would like to code a GMRES solver in python (no preconditioner for the time being) with the ability to restart. My end goal is to code a Flexible GMRES . However, I am facing some difficulties in understanding the restart part of GMRES(m). From , the algorithm for the GMRES(m) is No other Python object (list, dictionary, generator, Python sets) provides the flexibility of mathematical sets which our sets module tries to emulate. The second reason to use sets is that they are close to the entities which mathematicians deal with and it makes it easier to reason about them. Set objects conform to Pythonic conventions when possible, i.e., x in A and for i in A both work. Ich bin dabei ein Python Skript zu schreiben und will antürlich weg von Excel.
