MATLAB教材学习资料matlab的90个实例matlab的90个中的6-10 更新继续中(matlab studying)

sampencandApEn.m 为证明 样本熵 较 近似熵 更准确的程序 fast_ApEn1.m sampenc.m 为sampencandApEn.m的子程序(sampencandApEn.m sample entropy to prove more accurate than the approximate entropy procedure 3.fast_ApEn1.m sampenc.m subroutine is sampencandApEn.m)

MATLAB CODE FREQUENCY SELECTIVE SURFACE

说明：  遗传算法优化BP神经网络程序,很不错的，值得学习(GA for BP neural network training)

使用高斯列主元法和QR方法求解方程组，使用matlab编程.(Gaussian and QR column main element method for solving equations.)

二次规划的matlab源代码，很有用的优化工具！(Quadratic programming matlab source code, very useful optimization tool!)

A dynamic estimation of channel is necessary before the transmission of the signals since the wireless channel is time–varying..we use MMSE method for channel estimation. The MMSE method calculates the following, MMSE channel estimator is designed to minimize the estimation MSE. The MMSE estimate the channel responses.

3、 瑞利信道中的调制解调、信道估计： (1) 请推导出单径瑞利信道中的BPSK相干解调的理论误码率性能，并画出比特信噪比与误码率的关系曲线。 (2) 在单径瑞利信道中，请设计一种时分的导引辅助的信道估计方法，用Simulink进行仿真，测量BPSK的误码率性能，画出比特信噪比与误码率的关系曲线，并与(1)的曲线进行对比。 (3, the Rayleigh channel modulation and demodulation, channel estimation: (1) Please derive the single-path Rayleigh channel coherent demodulation of BPSK BER performance theory, and draw the signal to noise ratio and bit error rate curves. (2) single-path Rayleigh channel, please design a division of the guide-assisted channel estimation method, using Simulink simulation, measurement of the BER performance of BPSK, draw-bit signal to noise ratio and bit error rate curve, and with (1) of the curves were compared. )

介绍matlab中GUI的学习知识，值得对于matlab有兴趣的爱好者参考学习，我也在学习当中，还不错(Introduced in GUI matlab learning knowledge, it is worth for matlab interested enthusiasts refer to learning, I am also learning, good)

求图像信息熵，代码，MATLAB，m文件(Image entropy)
