design of rectangular microstrip antenna using MATLAB

说明：  四阶Runge-Kutta方法（微分方程）,并有例题(Fourth-order Runge-Kutta method (differential equation) with examples)

this is a MATLAB code for lattice boltzmann poisselus flow modeling

For estimation and prediction of random 2 dimensional motion using Kalman filter in MATLAB

这个函数返回n点2dw波段的傅里叶变换的DFT样本序列。通常情况下，以插值点的方式进行放大。(This function returns N point DFT samples of 2dw band of Fourier transform of a sequence. Typically, fft() returns N samples of Fourier transform ranging from 0 to 2pi. This function takes the N-point DFT samples and returns N-point samples corresponding to frequency band wc-dw to wc+dw.)

说明：  FIR数字滤波器的设计方法主要是建立在对理想滤波器频率特性作某种近似的基础上的。这些近似方法有窗函数法、频率抽样法、最佳一致逼近法。在这里只讨论窗函数法。程序中也是采用了这种方法。(FIR digital filter design method is mainly based on the frequency characteristics of the ideal filter for some kind of approximation on the basis of. These approximate methods are a window function method, frequency sampling method, the best uniform approximation method. Here only to discuss the window function method. Procedure is also adopted this approach.)

灰度等值线图matlab实现 灰度等值线图matlab实现1(gray contour map Matlab to achieve gray contour map to achieve a Matlab)

基于matlab将某个灰度值范围内的图像表现的更加突出，形成更好的对比。(Matlab will be a gray value within the image is more prominent, forming a better contrast.)

This is simulink model of Double-sideband full carrier/Conventional AM transmitter.

单基地正侧视条带式SAR仿真，采用的是RD算法(One base is side view of band SAR, RD Algorithm Simulation)
