LINEAR SYSTEMS SOLVER (for small Systems) (Scripts) Publisher's description
from Luigi Giaccari
SolverNxN is designed to solve many small linear system in a vectorized way in order to improve time perfomaces.
SolverNxN is designed to solve many small linear system in a vectorized way in order to improve time perfomaces. It is in practice a faster alternative to the matlab commands:
for k = 1:number_of_systems</span></span>
The Matlab looping speed can visibly slow down this process so most of the time is spent in the for loop and not to solve the system. This is particulary true when A is a small matrix. In this case SolverNxN can be a useful tool.
The speed improvement is more visibile the greater number are the systems and the smaller is their dimension.
The algorithm works assembling all the small elementary systems into a sparse matrix so the command is called just one time.
