LINEINTRGAL Line Integral in a 2D Vector Field. LINEINTRGAL(X,Y,U,V,C) computes the line integral along the lines given in cell array C. X and Y define the coordinates of a rectangular grid over which U and V are defined. X and Y must be monotonic and 2D plaid as ％ produced by MESHGRID. X, Y, U, and V must all be the same size.(LINEINTRGAL Line Integral in a 2D Vector-Fi eld. LINEINTRGAL (X, Y, U, V, C) computes the line integral along the lines gi ven in cell array C.

这是IIR数字滤波器的设计及滤波程序，IIR滤波器用matlab实现，滤波数据用C生成，主程序实现数字滤波(This is the IIR digital filter design and filtering procedures, IIR filter using matlab, using C to generate filtered data, the main program to achieve digital filtering)

P0301：数字图像矩阵数据的显示及其傅立叶变换 P0302：二维离散余弦变换的图像压缩 (P0301: the display of digital image data matrix and Fourier transform P0302: two-dimensional discrete cosine transform image compression)

matlab中不同信道估计的对比,对学习通信专业的学生很有帮助，主要介绍的是MIMO-OFDM系统下的信道估计。(matlab in the comparison of different channel estimation)

It s the Gabor filter using in Gist impelementation.

说明：  Matlab的 各种插值法..代码，Lagrange插值..Newton插值... Hermite插值... 分段低次插值... 三次样条插值 二维插值...(Various interpolation methods of MATLAB.)

本程序先生成一个“Blocks”信号，然后加上高斯白噪声，再用 db3 小波进行分解，(This procedure Mr. Cheng a " Blocks" signal, and then adding white Gaussian noise, and then ' db3' wavelet decomposition,)

画任意方向位置的圆柱体...希望有帮助哈(draw the 3d clinder in any diraction and position)
