Use a total-order index set to construct a polynomial chaos expansion.

Specification

Alias: none

Argument(s): none

Description

Use the traditional total-order index set to construct a polynomial chaos expansion. That is for a given order $p$ keep all terms with a $d$-dimensional multi index $\mathbf{i}=(i_1,\ldots,i_d)$ that satisfies

\[ \sum_{k=1}^d i_k \le p \]
