1 gaussian random variable generation and plotting using matlab code

一个空间桁架的优化粒子，与OPENSEES联合应用，求解速度较快，可供参考。(Optimization particle space truss, combined with OPENSEES solved faster, for reference.)

QPSK仿真，误码率计算及其仿真结果的比较(QPSK )

一维球坐标系下辐射传递方程切比雪夫配置点谱方法求解(One-dimensional spherical coordinates radiative transfer equation Chebyshev collocation spectral method for solving)

2d图像去卷积，增强图像对比度，去雾算法(2d image deconvolution, image contrast enhancement, deblurring algorithm)

Welch功率谱密度是用改进的平均周期图法来求取随机信号的功率谱密度估计值。Welch法采用信号重叠分段、加窗函数和FFT算法等计算一个信号序列的自功率谱估计(PSD如上例中的下半部分的求法)和两个信号序列的互功率谱估计（CSD）。MATLAB信号处理工具箱函数提供了专门的函数PSD和CSD自动实现Welch法估计，而不需要自己编程。(method of power spectral density plot )

基于三角波调制的单相pwm模型仿真，相关研究的人可以参考一下(Based on a triangular wave modulation of single-phase pwm model simulation studies of people can refer to)

通过飞下采样的轮廓博变换进行图像去噪，算法用MATLAB语言编写，更具文献进行编写的，可以直接运行(Fly through the outline of the sampling transform for image denoising, algorithm using MATLAB language to write, write more documents, can be directly run)

ofdm is the important technology for future wireless communication. battery power is constraint one. to improve this many energy efficiency scheduling are used along with power allocation technique

this programm is for nurbs toolbox in matlab to help plotting nurbs curves.
