说明：  地球物理勘探过程中对地震记录数据进行成像(Geophysical data during the imaging of seismic records)

该m文件为克里金插值程序，m文件里面附上了英文注释及例子。(The m file Kriging m file inside enclosed English notes and examples.)

最短路径dijkstra算法的MATLAB实现(MATLAB implementation of the shortest path Dijkstra algorithm)

说明：  lstm的matlab代码，里面有实际的例子可以参考(LSTM MATLAB code, there are practical examples to look at)

幅频键控ASK的相干调制解调以及非相干调制解调的仿真实现，源代码中作了详细的备注，通过学习该代码能够对ASK的调制解调有更加深入的认识(Coherent amplitude and frequency shift keying ASK modulation and demodulation, and non-coherent modulation and demodulation simulation, source code made detailed notes, by learning the code to the ASK modulation and demodulation of a more in-depth understanding of)

Record your voice for 5 seconds Play back the recording Store data in double-precision array Plot the waveform Calculate over all the frames in the sample LPF the speech at 900 Hz to remove upper freq. (since Pitch info. will be below 900 Hz) Perform Centre Clipping and find the Clipping Level (CL) Choose the appropriate clipping level Perform Center clipping Compute the autocorrelation calcute pitch Calculate the avg. pitch estimate for the whole sample X. Find Gender

主成分分析的matlab源代码，很有帮助，我已经用过好多次(principal component analysis)

相干信号源实现一二阶前后双向线性预测，绝对是好程序(Order to achieve a coherent signal before and after the bi-linear prediction)

Alamouti STBC coding for 2x2 mimo

This code is about spicking-deconvolution of seismic data.
