How to convert FORTRAN to MATLAB?

Converting from one programming language to other programming language may need some effort and understanding on both programming language. In this post, I will discuss about converting from Fortran to Matlab.

Fortran is general-purpose programming language developed by IBM. It is used primarily for numeric computation and scientific computation. Matlab is array-based programming language that used for scientific computation.

To convert from Fortran to Matlab, here are two alternatives you can do:
1. Convert manually
2. Convert automatically

==== 1. Convert manually =====
To convert manually, you have to understand both language very well. In the converting process, it will be easier for you to display your fortran code and your matlab side-by-side. If you have dual screen, it will be a lot easier. You can put your fortran code in second screen and your matlab in first screen. Or you can print your fortran code and put it beside your workstation.

==== 2. Convert automatically ====
I found a fortran to matlab converter from mathworks developed by Barrowes consulting ( To convert, followings are some steps needed:
1. Download and extract f2matlab into your computer
2. In matlab, go to the folder in which you extract f2matlab
3. In matlab command, put >> f2matlab('myfortran.f');
4. The f2matlab.m will do automatically for you

However, I noticed that some files cannot be converted correctly. Therefore, I have to do double check for the converted one. I noticed even some files cannot be converted at all. So, the f2matlab can help you a lot. However, be ready for manual checking and even manual conversion.

Hope this helps.

Find JIRA issues mentioned in Confluence Page

I have been walking through a lot of pages in internet but have not found any answer except one. However, the answer is not complete, so I will share my experience here. This feature is very useful, especially to summarize the issues found during certain tests, where the tests are reported in a confluence page. I found that there are so many questions about this, but Atlassian seems does not want to bother with this request. I found one way to do this by the following tricks Take one JIRA issue that related to the target confluence page (in this case, say it is GET-895) Find the global ID of a JIRA issue: It will show the JSON like this: [{"id":28293,"self":"","globalId":"appId=662e1ccf-94da-3121-96ae-053d90587b29&pageId=105485659","application":{

Mininet/Containernet Problem: Exception: Error creating interface pair (s2-eth5,s3-eth1): RTNETLINK answers: File exists

If you did not shut down the previous running mininet/containernet network (e.g. if you lose your connection to remote server), you will got the following error when you try to rerun your mininet network Traceback (most recent call last): File "./", line 31, in <module> net.addLink(d2, s1) File "build/bdist.linux-x86_64/egg/mininet/", line 403, in addLink File "build/bdist.linux-x86_64/egg/mininet/", line 430, in __init__ File "build/bdist.linux-x86_64/egg/mininet/", line 474, in makeIntfPair File "build/bdist.linux-x86_64/egg/mininet/", line 202, in makeIntfPair Exception: Error creating interface pair (d2-eth0,s1-eth2): RTNETLINK answers: File exists In order to solve the problem, you need to clean up the previous running topology by using the following command sudo mn -c It will clean up all your cache. It will be something like this $ sudo mn -c *** Re
