The bounds are suitable to determine the class of well-posed problems to ...
Gauss elimination through pivoting
Did you know?
WebIn the process of Gaussian elimination (with, say partial pivoting), applied to a sparse system, some zero entries of the working array may be filled with nonzeros. The set of such entries is called fill-in. Large fill-in leads to increasing both time and space used for … http://www-personal.umd.umich.edu/~fmassey/math473/Notes/c1/1.5.1%20LU%20decompositions%20with%20partial%20pivoting.pdf
