Is there any algorithm exist for improving matrix's reciprocal condition?
显示 更早的评论
for example;
1.0e6*
A=[42,1,0;43,0,0;44 1 1]
%A matrix inputs are badly conditioned but I cannot change the form because it is standart form for A matrix. Then I calculate;
N=A'*A %N looks very bad conditioned due to A
n=A'*L (L was determined before)
X=N\n
In conclusion, I cannot trust the results.

Instead of doing
X=N\n
you should be doing
X=A\L
