数值分析里面的高斯消元法利用全主元消去的程序(Numerical analysis method which use the Gaussian elimination procedure all main element elimination)

prediction - neural network code

一段用于光谱分析波段选择的连续投影算法matlab代码(A section for spectral analysis band selection continuous projection algorithm matlab code)

射频电路设计，微波设计中常常用到的smith原图，本程序利用MATLAB编程画出smith原图，可以帮助射频电路设计，比如画等功率匹配圆，等阻抗圆，等反射系数圆等。(RF circuit design, microwave design is often used smith artwork, this program using MATLAB to draw smith original programming that can help RF circuit design, such as painting and other power matching round, such as impedance circle, so the reflection coefficient circle and so on.)

说明：  行向量绘图，在matlab中对于含有大量的数据，单独在一张静态的图上是显示效果是很不理想的，这个程序实现了在matlab中以示波器的形式动态的显示器波形图(Row vector graphics in matlab in containing a large amount of data, alone in a static chart is to show the effect is not ideal, the realization of this procedure in matlab in the form of oscilloscope waveform display dynamic)

小波函数，网上找来共同学习，希望大家能用得着(Wavelet function, the Internet got to learn together, and hope that we can need it)

对信号分别无失真频率和失真频率带通采样得到采样后的频谱图(Signal distortion frequencies and distortion frequency bandpass sampling frequency spectrum after sampling)

新能源电动汽车动力锂电池模块的热模型simulink仿真分析(Thermal model simulink new energy electric vehicle lithium battery module simulation)

说明：  Isomap流形降维算法，包括了一个瑞士卷生成数据，dijk距离算法。(Dimensionality reduction algorithm Isomap manifold, including the formation of a Swiss roll data, dijk distance algorithm.)

This is code to simulation of AM, FM, PSK, QAM modulation
