This is DBSCAN source code and it is for matlab. Hope it will gonna be used.. :)

有符号的十进制数转十六进制数，以及CIC的simulink模型(dec to hex transfer)

利用fft求取一个信号的各次谐波的幅值和相角(Fft to strike a signal amplitude of each harmonic and phase angle)

Just a few functions used in my other toolboxes, for computing MSE and PSNR and some other less common image quality metrics.

MATLAB和Mathematica、Maple并称为三大数学软件。它在数学类科技应用软件中在数值计算方面首屈一指。MATLAB可以进行矩阵运算、绘制函数和数据、实现算法、创建用户界面、连接其他编程语言的程序等，主要应用于工程计算、控制设计、信号处理与通讯、图像处理、信号检测、金融建模设计与分析等领域。(MATLAB is a powerful language for technical computing. The name MATLAB stands for MATrix LABoratory, because its basic data element is a matrix (array). MATLAB can be used for math computations, modeling and simulations, data analysis and processing, visualization and graphics, and algorithm development.)

对二维图像进行离散傅里叶变换，分别给出了直流分量移动到频谱中心前后的频谱图样。(Two-dimensional images of the discrete Fourier transform, respectively, given the spectrum to move to the DC component of the spectrum before and after the design center.)

说明：  提供了MATLAB编程的经典实例,覆盖了大部分的实用功能。(MATLAB example)

混合扩频DS/FH仿真程序，从原始信号通过伪随机码，跳频码转变为混合扩频信号，再依次解跳解扩，最后通过低通滤波器恢复出信号。(Hybrid spread spectrum DS/FH simulation program, from the original signal by pseudo random code, frequency hopping code into a hybrid spread spectrum signal, and then hopping despreading, finally through a low-pass filter to recover the signal.)
