升余弦滤波器，matlab编程，从csdn上下的(raised cosine filter)

anny边缘检测算子是John F. Canny于 1986 年开发出来的一个多级边缘检测算法。 Canny边缘检测算法： step1:用高斯滤波器平滑图象； step2:用一阶偏导的有限差分来计算梯度的幅值和方向； step3:对梯度幅值进行非极大值抑制； step4:用双阈值算法检测和连接边缘。(anny edge detection operator is John F. Canny developed in 1986 out of a multi-level edge detection algorithm. Canny edge detection algorithm: step1: Gaussian smoothing filter image step2: first-order finite difference to calculate partial derivatives of the magnitude and direction of the gradient step3: the gradient magnitude non-maxima suppression step4: use dual-threshold algorithm for detecting and connecting edges.)

利用神经网络优化BP神经网络，能有效提高BP神经网络对非线性的拟合精度，效果较好。(Using neural network optimization BP neural network, BP neural network can effectively improve the accuracy of nonlinear fitting better.)

计算二维光子晶体的带隙和能带面，适合comsol3.5版本(Calculation of band gap and band surface of photonic crystal)

Vth-Vth0-Vsb for NMOS

这是几个不同形状参数的广义高斯分布的密度函数作图，以及形状参数的极大似然估计的程序。(This is several different shape parameters of the generalized Gaussian distribution density function mapping, as well as the shape parameter of the great likelihood estimation procedures.)

matlab code for pitch of speech signal

这个matlab程序实现了目标对象的图像分割与提取技术，附件里的程序以车牌的检测与识别为例，效果非常好。(The matlab program to achieve the target image segmentation and extraction technology, the annex of the procedures for license plate detection and recognition, for example, the effect is very good.)

匹配追踪和正交匹配追踪，GPS和INS组合导航程序，有借鉴意义哦，详细画出了时域和频域的相关图，抑制载波型差分相位调制，阵列信号处理的高分辨率估计，使用matlab实现智能预测控制算法。( Matching Pursuit and orthogonal matching pursuit, GPS and INS navigation program, There are reference Oh, Correlation diagram shown in detail the time domain and frequency domain, Suppressed carrier type differential phase modulation, High-resolution array signal processing estimates, Use matlab intelligent predictive control algorithm.)
