MATLAB: Using SVD to solve systems of linear equation: have to implement direct parameter calibration method

direct parameter calibration methodMATLABsvd

can you please tell me how to implement direct parameter calibration method in matlab to show how SVD is used to solve systems of linear equation? i know about SVD but dont know any matlab syntax for direct parameter calibration method.

Best Answer

Given an n-by-n linear system
   A*x=b
and the SVD of A,
[U,S,V]=svd(A,0);
Then one could solve the system as follows
x= V*((U'*b)./diag(S))
However, the easier way would be
x=A\b
so I don't understand why you stipulate that the SVD has to be used. If this isn't what you want, please elaborate and maybe also explain the niche terminology "direct parameter calibration method".
