How to change the size / ratio of a figure
Perhaps as follows? axis tight dx=diff(xlim); dy=diff(ylim); xmax=dy/(9/11)/2; xlim([-xmax,+xmax])

solving a system of linear equations where A is a 40*40 sparse matrix
You should use \. It's not just about precision, though. It's also about speed: A=sprand(400,400,0.2)+speye(400); b=rand(400,1...
