Built-in Matlab speed-up

自己编写的全主元高斯消去法解线性方程组的matlab函数。特点：运行稳定，适合于工程计算；结构清楚，注释详尽，非常适合于初学者。(their preparation of all PCA Gaussian elimination method for solving linear equations of Matlab function. Features : stable operation, which is suitable for engineering calculations; Structure clear, detailed notes, which is very suitable for beginners.)

这是一个基于光信道（考虑色散）的OOK调制，其中看空比为63 (This is a OOK modulation based optical channel (taking into account dispersion), which bearish on the ratio of 63 )

一个很好地主元分析（PCA）程序~~~~~~(A good Principal component analysis program！)

matlab编写的基-2fft快速付里叶算法程序，输入倒位序，输出自然顺序。(Matlab prepared by the base-2fft fast Fourier algorithm procedures inversion input sequence, Output of natural order.)

这个 压缩包含有完整的QPSK-MSK-QAM-OFDM调制解调m程序。希望对大家有帮助(This includes a complete compression QPSK-MSK-QAM-OFDM modulation and demodulation m program. We want to help)

说明：   这些程序,用于模拟仿真非线性动力学的分岔,混沌等动力学行为(it s for the nonlinear dynamics phenomenon of code.)

QPSK信号通过瑞利衰落信道后的误比特率和误符号率，并与AWGN信道下的误比特率和误符号率进行对比。其中，多普勒频移为 100Hz，经过矩形脉冲成形后的抽样时间间隔为1/800000s。(The QPSK signal harms the bit rate after the Rayleigh fading channel and harms the mark rate, and harms the bit rate with the AWGN channel under and harms the mark rate to carry on the contrast. And, the Doppler shift is 100Hz, after undergoing the square pulse forming the sampling time gap is 1/800000s. )

SAR图像变化检测,可以对比同一地点不是时间的SAR图像变换，并聚类分析(SAR image change detection, you can compare the same place time of SAR image transformation and cluster analysis)
