matlab图形对象的属性讲解资料。详细收录了matalb图形对象的属性说明。(matlab graphical information to explain the properties of the object. Contains details of the properties of graphic object description matalb.)

说明：  算差分盒维数的matlab程序。 让窗口中的每个像素都对分数维作出贡献。首先,计算某一尺度窗口的平均灰度值 ,然后判断每一个像素的灰度 ,若大于灰度平均值 ,则累加其灰度值为 max ,若小于灰度平均值 ,则累加其灰度值为min ,用max 和min代替 在 Sarkar 和 Chaudhuri 算法中的最大值和最小值 ,再通过拟合求出分数维。 (Differential count box dimension matlab program. Let window on the fractal dimension of each pixel to contribute. First, the calculation of an average gray scale of the window, and then determine the gray scale of each pixel, if the intensity is greater than the average, the cumulative value of its gray max, if less than the average gray level, the accumulation of its gray value of min, max and min to use instead of the algorithm in Sarkar and Chaudhuri maximum and minimum, and then by fitting the calculated fractal dimension.)

信号被窗函数截断，并做频谱分析，比较汉宁窗、三角窗等的特点(Window function signal is cut off, and do spectral analysis, comparing Hanning, triangular windows and other characteristics)

802.11协议里面牵扯到的OFDM技术。(802.11 protocol which involves the OFDM technology.)

逆变器的预测电流控制，包括M文件和SIMULINK 模型，已经仿真验证(predictive current control of inverter,including M file and SIMULINK model)

说明：  粒子群算法优化广义回归神经网络的代码，具有很好的借鉴意义。(Particle swarm optimization (PSO) algorithm optimizes the code of generalized regression neural network, which has a good reference value.)

说明：  MATLAB 即有内建的解决很多通常遇到的曲线拟合问题的能力， 又具有附加这方面的 产品。本技术手册描述了几种拟合给定数据集的曲线的方法(MATLAB built-in solution that is often encountered in many curve fitting problems, but also has additional products in this area. This technical manual describes several data sets fit the curve of a given method)

HYBRID returns the output vector Y and the control vector UC of a hybrid system which is defined by Np, Dp, Nd and Dd. The transfer function of the continuous time plant is stored in Np and Dp. Nd and Dd are the numerator and denominators

计算时间信号序列的谐波总畸变率，同时课计算基波的幅值和相位，典型应用于电力信号分析。(The total harmonic distortion signal sequence computation time, while computing the fundamental lesson of the amplitude and phase of the signal analysis is applied to a typical power.)

数据类型转换,int转换成uint8，比较适用(data change)
