说明：  MMC中IGBT损耗计算与结温模块（计算开关周期内的损耗，公式可以参考 电工技术学报 WXP先生 2018-12-14 的一篇文献），还有一对VT+VD的Foster。公式及其实现没有问题，仿真过程可能出现代数环，如果有自己的Foster或者Cauer最好。(power loss calculation&junction temperature detection of IGBT in MMC)

说明：  一篇很好的奇异值分解的论文 是针对数字图像的(A singular value decomposition of a good thesis for digital images)

本文首先介绍了几种LDPC码的编译码算法，同时推导了译码错误概率和密度进化 过程，讨论了信道参数的门限效应。接着对LDPC码二分图中长度为4的环进行了深入 研究，提出了一种LDPC码校验矩阵的消4一环生成算法，采用Matlab和VC++融合编程 方式，完成了此算法的程序设计。此算法不仅可生成二进制LDPC码的校验矩阵，并且 对算法修正后，也可生成多进制LDPC码的校验矩阵。采用此算法后可避免LDPC码译 码过程中的重复迭代，显著提高了短帧LDPC码的误比特率性能。同时对不同参数对 LDPC码性能的影响进行了仿真，得到了一些结论。最后，利用VHDL语言在复杂可编 程逻辑器件(CPLD)上完成了LDPC码编码器的硬件实现。另外，给出了LDPC码译 码器硬件实现的整体结构图，结合对数似然比域内的置信传播迭代译码(LLR-BP)算 法，对译码器的各个模块进行了详细阐述。(Research and implementation of LDPC coding and decoding technology)

This guide can draw a mandelbrot figure. In default values it calculates Z=Z^2+C for 20 iterations, where Z initally equal to zero and C has the values of every pixel created by meshgrid function(built-in). although mandelbrot equation is Z=Z^2+C you can change the degree of the equation between 1 - 50. higher number in iteration, points in axes gives better results in image besides more resulting time. to zoom an area of the figure you must aproximately choose the point and then change the center values to this point values then push Show Graph button. because of this is the first version there can be any lack of usage.
