This code uses lagrange interation to calculte user s position in indoor case.

gui编程中有用的几个程序段，值得借鉴学习学习(Several useful gui programming block, is worth learning learn)

一种常用的插值计算方法，普通克里金法，采用球状模型的半变异函数。(A common interpolation methods, ordinary kriging method using spherical model semivariogram.)

基于matlab的锁相环的仿真，注释详尽(Phase-locked loop based on matlab simulation, comments in detail)

脉冲编码调制（PCM）用于在数字传输媒体上传送模拟信号，在PCM中，首先对模拟信号以高于其带宽两倍的奈奎斯特率进行采样，然后对所得样本进行量化。采用不同量化级别生成的PCM编码会影响接收器重建模拟信号的质量。 (Pulse code modulation (PCM) for the media in the digital transmission of analog signal transmission in the PCM, the first analog signal to more than the Nyquist rate of twice the bandwidth sample, and then to quantify the samples. Using different quantization level generated PCM coding receiver will affect the quality of the reconstruction of analog signals.)

通过用MATLAB软件解决七参数转换转换的编程代码(Seven parameter transformation)

SparseArrays map integers to Objects. Unlike a normal array of Objects, there can be gaps in the indices. It is intended to be more efficient than using a HashMap to map Integers to Objects.

本程序为抗JPEG压缩的半脆弱性彩色图像数字水印，主要原理为DCT转换和DCT系数比较法，内含5中攻击仿真测试以及GUI界面，测试环境为MATLAB2009a，系本人2013年本科毕业设计(The procedures for the anti-JPEG compression semi-fragile color image watermarking, the main principle is the DCT transform and DCT coefficients comparative law, including five in the attack simulation testing and GUI interface, the test environment is MATLAB2009a, Department I graduated design 2013)

matlab源程序 有点小错误但是稍微改下就可以了 人工免疫用于故障诊断源程序(matlab source code to change a little wrong, but under it a little artificial immune source for troubleshooting)

利用Matlab软件对OFDM技术的原理,调制解调过程进行了仿真实现(Matlab software on the principle of the OFDM technology, modulation and demodulation process simulation)
