Data Visualization Via MATLAB (3 dimensional data)
MATLAB #PlotData Visualization Via MATLAB (3 dimensional data)The three dimensinal data are composed of matrix. Its data also has the position matrix. (x,y,z). We can plot the isosurface, contourlines, slice plots etc for this kind of data.
3d Contour Surface PlotsWe should extract the contour data via the function isosurface. Though I have completed the figure, I can’t understand the reason. I will give issulation later.

3D contour plot via Mayavi
Python #PlotRecently I am interested in the data visualization and I have try different plots. Previously in my research work I ploted a 3d contour figure via MATLAB. Since the frequently used Python package Matplotlib has poor support on this kind of 3d data visualization. I also tried the Mayavi package before and I didn’t learn it well.
After reading a lot of examples I begin to control the skill of using Mayavi. I try to replot the original plots via python.
Here is the process. We firs ...
A rotated 3D contour plot via Mayavi
This figure is the Fig2 of my research work and I let it rotated.
This time I try o plot the 3d animated distribution via python package Mayavi
Different from the animated operation via using the Matplotlib, This 3d data visualization is more powerful.
I only upload the figure this time and I will write a complete note latterly.
The data are calculated via parameter sweep and store with txt format. We need load it

Sublime的安装及使用究极总结
SublimeSublime Text 3 的安装及使用目前的编辑器非常多,比如Sublime,Atom, Vs Code等,都各有优劣。目前来看VS Code应该是份额最高、功能最全的。即使这样,也还有其不如人意的地方,比如一般开启比较慢。Sublime Text 3 是我大三时候经朋友推荐开始使用的,一直用到了现在博三(2019 12 28),用这款编辑器写过MATLAB, Python, Bash脚本, Markdown, Latex等,对其特性还是比较了解的,本片笔记将会从安装开始,详细写下Sublime Text 3 的安装及配置以及一些插件的使用。
软件安装Windows 平台直接去Sublime Text 3 官网下载对应的版本,最好选Windows的exe版本而不是portable version。下载好后一路点击安装确定就好了。
Linux 平台官网也有安装教程,以Ubuntu为例
Install the GPG key:
1wget -qO - https://download.sublimetext.com/sublimehq-pub.gpg | sudo apt ...
A rotated flower plotted via python (animated)
Python #PlotAll the python study code can be found in my own repository.
As a study of Python data visualization, I plot a 3D follower and let it rotated horizontally. The packages I used are

The follower is defined via the following data

Useful Git Command
GitSimple useIn this note I will summarize the simple use of Git. How can we create new repository and upload the local folders to remote? Or after we changes or add new files, how can we update the changes?
1. Create new repositoryWe should create new repository in the remote. Then we clone the remote repository into local folder. We can make changes on the folder and update the changes via
123git add .git commmit -m "changes"git push -u origin master
”-u“ is for the first update.

inkscape安装插件textext出错的解决办法
Inkscape #Darw问题解决:是因为自己的插件版本于inkscape版本不一致造成的。
具体过程近几日要画一些带公式的矢量图,发现inkscape非常好用,尝试安装插件textext时,却出了问题,我直接在该网站下载了最新版,根据官方教程安装了inkscape0.92.4以及推荐的pdf2svg)
安装好后,开始运行该软件的依赖测试文件 ,接下来就是一连串错误。
