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.

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".
