Method ao/spsdSubtraction
SPSDSUBTRACTION makes a sPSD-weighted least-square iterative fit
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
DESCRIPTION: SPSDSUBTRACTION makes a sPSD-weighted least-square iterative fit
CALL: [MPest, plOut, aoResiduum, aoP, aoPini] = spsdSubtraction(ao_Y, [ao_U1, ao_U2, ao_U3 ...]);
[MPest, plOut, aoResiduum, aoP, aoPini] = spsdSubtraction(ao_Y, [ao_U1, ao_U2, ao_U3 ...], pl);
The function finds the optimal M that minimizes the sum of the weighted sPSD of
(ao_Y - M * [ao_U1 ao_U2 ao_U3 ...] )
if ao_Y is a vector of aos, the use the matrix/spsdSubtraction is
advised
OUTPUTS: - MPest: output PEST object with parameter estimates
- aoResiduum: residuum times series
- plOut: plist containing data like the parameter estimates
- aoP: last weight used in the optimization (fater last
Maximization/Expectation step)
- aoPini: initial weight used in the optimization (before first
Maximization/Expectation step)
