matlab

说明：  综合了各种基于matlab直接序列扩频通信系统的文档(Integrated a variety of direct sequence spread spectrum based communication system matlab documentation)

汇集了几个经典的matlab程序，大家共同学习(A collection of several classic matlab program, we learn together)

用C++编写的xu-white模型，适合砂泥岩地层岩石物理建模，很实用(Written by C++ xu-white model, suitable for sand-shale formation rock physics modeling, it is practical)

一维插值，里面含有一个实例，并且有计算机结果图。(One-dimensional interpolation)

matlab檔案，用於計算定位成功率，輸入nmea檔案，自動計算NMEA定位的成功率(Calculate the fix yield rate)

extract zero cross rate features from an audio signal

对采集到的信号进行快速傅里叶变换，可以实现对信号频谱分析(The collected signals fast Fourier transform, spectral analysis of the signal can be achieved.)

用UTD方法分析电大导体表面上缝隙天线间的互耦(UTD mutual coupling analysis method used on TV antenna gap between the surface of the conductor)

This file is the program to change decimal number to binary number.

非线性最小二乘优化问题以误差的平方和最小为准则来估计非线性静态模型参数的一种参数估计方法。设非线性系统的模型为y=f(x，θ)，常用于传感器参数设定。(64/5000 A parameter estimation method based on the minimum sum of squares of errors. Suppose that the model of the nonlinear system is y=f(x,), which is commonly used for sensor parameter setting.)
