摘要翻译:
现实生活中的许多问题都可以归结为一个复指数逼近问题的求解,而这个问题通常是病态的。最近在一个理论框架中提出了一种新的求解方法,即平面上的特定矩问题。在这项工作中,为了使这个新工具在实践中有用,我们解决了一些计算问题。提出了一种算法,并用于求解一个核磁共振波谱分析问题、两个时间序列插值和外推问题以及一个矩量形状问题。

英文摘要:
Many real life problems can be reduced to the solution of a complex exponentials approximation problem which is usually ill posed. Recently a new transform for solving this problem, formulated as a specific moments problem in the plane, has been proposed in a theoretical framework. In this work some computational issues are addressed to make this new tool useful in practice. An algorithm is developed and used to solve a Nuclear Magnetic Resonance spectrometry problem, two time series interpolation and extrapolation problems and a shape from moments problem.
