getCoeff	Retrieve the coefficients in the ith PSD term
getLinExpr	Retrieve the linear expression contained in this PSD expression
getPsdVar	Retrieve the PSD variable in the ith PSD term
getValue	Retrieve the value of this PSD expression after the problem is resolved
remove	Delete the ith PSD term from this PSD expression
remove	Delete All PSD terms that contain the specified PSD variable
size	Retrieve the number of PSD terms contained in a PSD expression
