分形，是以非整数维形式充填空间的形态特征。分形可以说是来自于一种思维上的理论存在。(Fractal, is filling in the form of non-integer dimension of space morphology. Fractal can be said to come from the existence of a theory of thinking.)

变压器油中溶解气体的故障诊断方法，即IEC三比值法。用Matlab 程序运用的结果进行整理而得到的约简后的故障诊断决策表(Dissolved gases in transformer oil fault diagnosis method, that is, three-ratio method IEC. Matlab program used to collate the results of the application obtained after reduction of the fault diagnosis decision table)

about the signal processing,especially the fourier transform

对于学习信号处理的同学们，需要数值分析的一些知识，如拟合、松弛迭代等等都是有用的数值分析方法(For students studying signal processing, numerical analysis requires some knowledge of relaxation that a useful method for numerical analysis)

能够计算出一个图像矩阵的灰度梯度共生矩阵，并计算出其协方差(To calculate an image matrix of gray gradient co-occurrence matrix, and calculate the covariance)

matlab程序，可用来读取rinex文件(matlab processing，can be used to read rinex files)

说明：  此程序是做全息合成孔径实验室用于把几幅不同角度拍摄的全息图的再现像叠加到一起，达到提高分辨率的效果(This procedure is done holographic synthetic aperture laboratory to make the pieces of the same map superimposed together to achieve the effect of improving resolution)

进行可靠度分析有效方法 画出数据概率分别vu 如 (for reliable method N = FREQDM(Y) bins the elements of Y into 10 equally spaced containers and returns the frequency of each container. If Y is a matrix, FREQDM works down the columns. N = FREQDM(Y,M), where M is a scalar, uses M bins. )

通过调用DSP builder中的设计模块设计的DDS，已经验证通过，可调节频率字来调节输出频率(Through the design module called DSP in the builder DDS, which has been verified by word frequency, can be adjusted to adjust the output frequency)
