Parameter estimation of monomial-exponential sums in one and two variables

作者：

Highlights：

• We propose a matrix-pencil method to identify monomial-exponential sums.

• In the univariate case, it is based on the QR factorization of Hankel matrices.

• In the bivariate case, it assures the same accuracy of the univariate case.
