Calculate the coefficients of a polynomial chaos expansion using the singular value decomposition.
Alias: none
Argument(s): none
Calculate the coefficients of a polynomial chaos expansion using the singular value decomposition. When the number of model runs exceeds the number of terms in the PCE, the solution returned will be the least-squares solution, otherwise the solution will be the minimum norm solution computed using the pseudo-inverse.
