说明：  求x的算术平方根，保留N位有效数字，并返回算术平方根的平方(solving the square root of x with N digits Significant figures, and saving the Square root of the square)

Amplitude modulation and demodulation using simulink and matlab.

用MATLAB实现快速傅里叶变换。方程有需要的话，可以自己设定(Using MATLAB to achieve fast Fourier transform. Equation there is a need, they can set their own)

用二维热传导分数步长法求解二维热传导方程，其中解转化来的方程用的是追赶法,分别用了ADI,LOD,对称LOD方法进行求解(Solving the two-dimensional heat conduction equation with two-dimensional heat conduction fractional step method, Solving the two-dimensional heat conduction equation with two-dimensional heat conduction fractional step method, which transformed to the equation solution is to catch up with the law, respectively, with the ADI, LOD, LOD method for solving symmetric)

一种计算多重分形谱的算法，能够有效计算多重分形谱的各种参数(A method of calculating the multifractal spectrum)

说明：  在MATLAB中用共轭梯度法求解非线性函数的优化问题。(The conjugate gradient method is used to solve the optimization problem of nonlinear functions.)

single phase active harmonic filter

说明：  说明： 该课题为基于bp神经网络的中文汉字识别系统，可以用手写板写，现场识别。有界面GUI操作。另外可识别汉字，字母，数字等均可。(Explain: This project is a Chinese character recognition system based on BP neural network, which can be written on handwritten board and recognized on the spot. There is interface GUI operation. In addition, it can recognize Chinese characters, letters, numbers, etc.)

FRFT和线性调频信号中的子程序，FRFT中的a，也就是需要估计的角度。两个程序需要一起使用(FRFT and chirp signal subroutine, FRFT of a, is the need to estimate the angle. Both programs need to be used together)
