这个文章说明了格雷算法在心电信号处理上的应用(The paper proposes a learning algorithm for real-time analyzing the gray relations between templates and test electrocardiogram (ECG) signal patterns. Without analyzing relations between the test ECG pattern and every template in the database for the recognition, several training patterns for the learning algorithm are chosen from an ECG waveform database with patient diagnosis information, and then the training result is used to analyze the test ECG.)

求解微分方程（这里指的是常微分方程）指含有一次、二次、乃至高次微分未知数的方程。是解决偏微分方程、数理方程的基础。有许多特殊函数，都是为了无法得出多项函数或超越函数型式的解析解的微分方程而定义出来。这些特殊函数之所以重要，是因为它们描述了自然界中的某些现象，例如，电子的活动、鼓皮的振动、钟摆的摆动等等。(Solve differential equations (in this case is the ordinary differential equation) means containing one, two, and even high-differential equations unknowns. Is to solve the partial differential equations, mathematical equations based. There are many special functions, are not drawn to a number of functions or functions beyond the type of analytical solution of differential equations which define them. These special functions are important because they describe the nature of certain phenomena, for example, electronic activities, drum skin vibrations, pendulum swing, and so on. )

编写的一维非均匀傅里叶变换代码。不需要使用mex编译c文件或fortran文件。通过代码可了解NUFFT的技术细节。(One dimensional non-uniform Fourier transform code written. There is no need to use mex to compile C files or FORTRAN files. You can understand the technical details of NUFFT through code.)
