信号发生器 能产生随时间变化的信号 可以任意设定信号形状(Signal generator to produce time-varying signal)

自己编写的一个大批量不同类别数据录入程序，并且为防止因为数据量太大导致程序运行缓慢，将其改写成分批小规模数据。方便了大规模数据处理慢带来的各种不变。(I have written a large quantities of different types of data entry procedures, and because the amount of data in order to prevent too much causes the program to run slowly, be rewritten into small batches of data. Facilitate the large-scale data processing slow and the various unchanged.)

希尔伯特黄变换的C语言实现，包括希尔伯特谱分析，瞬时频率的求解等。(Hilbert Huang Transform C language, including Hilbert spectral analysis, such as instantaneous frequency solution.)

主要编写了生活中几个常用的函数：二次函数、分段函数。(Mainly to write several commonly used functions in life, quadratic function, piecewise function.)
