CircuitAnalysisIIwithMATLAB

说明：  matlab发送端程序,256位FFT,16QAM-OFDM，最后有时域和频域图形显示(matlab sender program, 256 FFT, 16QAM-OFDM, the last times and frequency domain graphics)

抓取电脑屏幕。利用MATLAB实现print screen的功能(Capture the computer screen. Use MATLAB to achieve print screen function)

使用matlab语言，用7种方法绘制立方体，有详细说明和配图。对于了解matlab三维绘图的基本语句有借鉴作用。初学者非常适合。(Using matlab language, with 7 kinds of methods of drawing a cube, with a detailed description and distribution map. Matlab for the understanding of the basic sentence of three-dimensional graphics are used for reference. Very suitable for beginners.)

电压暂降原始信号和小波分解程序，加入白噪后的信号及其小波分解程序，使用不同阈值方法去噪的比较，并对其波形读取，确定暂降的开始和结束点，功能强大。(Voltage sag original signal and wavelet decomposition process, after adding white noise signal and wavelet decomposition, the use of methods to compare different threshold de-noising, and its waveform is read to determine the sag of the start and end points, and powerful.)

说明：  matlab中priny toolbox原理(Principles of priny toolbox in matlab)

趋势面分析是拟合数学曲面的一种统计方法。通常要找到一个合适的曲面精确表达实际问题往往比较困难，但却可以利用多项式函数来近似逼近它。(trend surface analysis is fitting surfaces of a mathematical statistical methods. Usually to find a suitable surface accurately reflect the actual problems are often more difficult, but polynomial function can be used to approximating it.)

in this package are the programs needed to solve any problems boundary value differential.
