基于matlab的有限元程序源代码，希望大家喜欢(Based on the finite element program matlab source code, I hope everyone likes)

说明：  对ask fsk用matlab写出 并有图像(that is a good thing)

关于混沌Kolmogorov熵的计算程序，在前人基础上自己编写的。已经用过很多混沌时间序列K熵的计算。(On chaotic Kolmogorov entropy calculation procedure, based on predecessors have written. Has been used a lot of chaotic time series K entropy calculations.)

说明：  主要是些简单的数字图像处理中基本的知识点(Mainly some simple digital image processing knowledge of the basic points)

Converts a floating point value to IEEE 754 32 bit binary representation. Sign Bit: 1 Exp: 2 to 9 Frac: 10:32 Single-precision floating-point format is a computer number format that occupies 4 bytes (32 bits) in computer memory and represents a wide dynamic range of values by using a floating point. In IEEE 754-2008 the 32-bit base 2 format is officially referred to as binary32. It was called single in IEEE 754-1985. In older computers, other floating-point formats of 4 bytes were used. For example, the 32-bit floating point bit pattern 1 01111101 00101100000000000000000 is interpreted as the following: (− 1)1 × (1 + 0.34375) × 2(125–127) = -1.34375× 2− 2 = -0.3359375 ​

信号的读取及方差计算程序，用于计算信号的误差及统计(Readout and variance calculation program for calculating a signal error and Statistics)

说明：  分析了LTE系统频率偏移，定时误差，信道估计问题等，并对广义Rake接收机和CPEDS接收机的性能做了比较。(Analysis of the LTE system frequency offset, timing error, channel estimation problems, and generalized Rake receiver performance receiver and CPEDS were compared.)

基于 MATLAB 的时域信号采样及频谱分析，是很好的学习时域信号的matlab源代码。(MATLAB-based time-domain signal sampling and spectral analysis, is a very good study of time-domain signal matlab source code.)

对二值图像（黑白图像）每行值进行RUN-LENGTH编码和解码(pair of two binary image (black-and-white images) per line value RUN-LENGTH coding and decoding)

描述TV HDMI 输入源的信号侦测及Parser过程。(Description HDMI signal input source detection process.)
