What is scaled partial pivoting?












0












$begingroup$


I have been reading this topic about scaled partial pivoting. And I'm not able to figure out some things like when should we use scaled partial pivoting in a matrix?
And if the first entry in the first row has the highest value in its respective column i.e. first column then should we still interchange the rows?
