this is a matlab program

this code about optimization

龙贝格积分，MATLAB程序，计算方法作业，内有说明(Romberg integration, MATLAB procedures, calculation methods work, there are instructions)

包含五个文件夹。 （1）MATLAB程序：其中包含10余个MATLAB程序或（函数）的源代码。程序中所作的注释，与书中关于对应算法的描述是一致的 （2）二值图像：其中的图像可供形态学图像处理实验用，也可通过提取对象的边界，供曲线演化实验使用。 （3）灰度图象和彩色图像：其中的图像，可以作为图像分割，平滑滤波，反差增强，彩色增强以及图像放大等实验的素材。 （4) 视频剪辑：，"two_cells"是采用改进的变分水平集方法，实现GAC模型图像分割的演化过程；"denoissing"是利用P_M方程，对图像平滑去噪的演化过程 "curve_linear_heat_flow"是利用FT实现的闭合曲线的线性热流演化过程。 (These codes are focused on PDE image processing)

MATLAB绘图时，用于生成带有箭头的平面坐标系，方便绘图，更显专业(Two-dimensional coordinates with arrow.)

This matlab code generates UWB indoor channel impulse response described in : Cassioli, D. Win, M.Z. Molisch, A.F., "The ultra-wide bandwidth indoor channel: from statistical model to simulations," Selected Areas in Communications, IEEE Journal on , vol.20, no.6, pp. 1247-1257, Aug 2002 URL: http://ieeexplore.ieee.org/stamp/stamp.jsp?arnumber=1021916&isnumber=21989 All parameters of the channel were taken from the reference paper

高频地波雷达单基地一阶和二阶海杂波程序，毕业设计做的东西(High-frequency surface wave radar monostatic first-order and second-order sea clutter program)

基于DFT的瞬时测频算法，及插值算法，最后由图形表示测频结果。(Based on the Instantaneous Frequency Measurement DFT algorithm, and the interpolation algorithm, and finally by the graphical representation of frequency measurement results.)

说明：  一种有效的滤波算法，通过比较特定区域内的像素点的邻域均值来进行图像的去噪滤波。(An effective filtering algorithm, by comparing the particular pixel within the region to the neighborhood mean filter for image denoising.)
