基本ESPRIT谐波分析算法的Matlab程序。

简介：
This function, designated as ‘myesprit,’ is designed to implement an algorithm for detecting interharmonic distortion, as detailed in “A Fast TLS_ESPRIT-Based Algorithm for Interharmonic Detection” by Zhang Bin Sheng. The function’s primary purpose is to analyze raw data and produce a fitted dataset. Specifically, the input parameters include: ‘x,’ representing the original data; ‘M,’ denoting the time window width; and ‘dt,’ specifying the sampling interval. The function yields several outputs: ‘jx,’ which contains the fitted data; ‘Ad,’ indicating the amplitude; ‘Qd,’ representing the phase; ‘ad,’ signifying the decay factor; and ‘fd,’ denoting the oscillation frequency. The overall result is presented as a structured array comprising these four components: amplitude, phase, decay factor, and oscillation frequency.
