power_switching_power_supply_lib.rar,功率电子领域matlab仿真文件，已经验证过，程序运行正常(power_switching_power_supply_lib.rar,Power electronics field matlab simulation file, has already been verified, the normal operating procedures)

余弦分析采用最小二乘法，以适应一个正弦波的时间序列。余弦分析通常用于生物时间序列分析，演示predictible的节奏。这种方法可用于一个不平等的间隔时间序列。(Cosinor analysis uses the least squares method to fit a sine wave to a time series. Cosinor analysis is often used in the analysis of biologic time series that demonstrate predictible rhythms. This method can be used with an unequally spaced time series.)
