matlab snopt 学生版,求解大规模非线性规划问题(matlab snopt Student Edition, for solving large-scale nonlinear programming problem)

Prony算法用来提取信号的幅值、频率、衰减因子和初相角。它在电力系统低频检测，谐波检测等方面运用非常广泛，但是缺点是抗噪性差，它的信号提取能力强，模拟曲线的能力强，但为了提高它的抗噪性，最好与其它方法相结合(The Prony algorithm is used to extract the amplitude, frequency, attenuation factor and initial phase angle of the signal. It is in the power system low frequency detection, harmonic detection and other aspects of the use of a very wide range, but the disadvantage is poor anti-noise, and its signal extraction ability, simulation curve ability, but in order to improve its anti-noise, the best and other methods Combine)
