汽轮机转子系统前三阶临界转速的传递矩阵法(Turbine rotor system critical speed before the third-order transfer matrix method)

metodos numericos interpolacion segundo grado

说明：  应用于并网的分布式发电或微网系统 PQ控制要求电站的有功和无功是可控的(The distributed power generation or microgrid system PQ control applied to the grid requires that the active and reactive power of the plant is controllable)

image color segmentation.... very useful code

说明：  《MATLAB 7.0编程基础基础》源程序，适合初学者使用，第4章(&quot MATLAB 7.0 programming foundation base&quot source, suitable for beginners, Chapter 4)

信号与系统matlab作业，实现卷积操作，供学习信号与系统的同学们参考(1. Define two signals as: x1[n] =   n, 0 < n  N1+1 2 N1 − n+ 1, N1+1 2 < n  N1 0, elsewhere and x2[n] =  1, 0 < n  N2 0, elsewhere We let N1 = 999 and N2 = 500. (a) (30 )Write a MATLAB function myconv to compute x1[n]x2[n] where  denotes the convolution sum. You have to plot your result and attach it in your report. You may use the MATLAB function conv to check whether your result is correct.)

说明：  利用PQ分解法进行电网潮流计算，得出待求解电网的各PQ节点的有功功率和无功功率，各PV节点的有功功率和节点电压(Make use of power flow PQ decomposition method calculated the PQ to be solved for each grid node of active and reactive power, active power and node voltage of each PV nodes.)

source code for curve fitting PSO

实现用systerm generation 完成fft变换。原理清晰，但是结构相对复杂，请大家认真看原理，来自日本书。(Systerm generation completed using fft transform. Principles of clarity, but the structure is relatively complex, please look carefully the principle of everybody, from the Japanese book.)

这个源码包含了LT码的编码和解码过程啦。(The orginal code includs the encoding and decoding process of LT code)
