This contains some workarounds for annoying bugs in MATLAB's publish function

Some workaround to common problems with MATLAB's publish()

Slow scatter

Problem: Horrible slowdowns when using scatter() in a script that you want to publish Solution: Don't use scatter. Use plot(x,y,'.') instead.

Combinatorial Figure mess

Problem: Horrible slowdown when publishing a document that has many figures in it. Symptom: You will see MATLAB cycling through all open figures. This means that it does something like this:

How to make your own file sharing service

What you want to do

Create a small utility that takes a folder you want to share, and creates a not-obvious URL that you can send to other humans.

What you need:

  • A server you can SSH into
  • a *nix machine

Determine if this MATLAB function is being called by another function, and if so, what is it? The power of dbstack

How to find out if your MATLAB function is being called by another function or not

calling_func = dbstack;

if calling_func is non-empty, it is being called by some other function (as opposed to being called directly by the user from the command prompt)

How to find out the name of the function calling the current function

Handy hashing for PDFs made by MATLAB code

Automatic Version control for publish()

MATLAB's publish takes a script and makes a PDF from it. Here, we want to add some basic info about the file that created the PDF to the PDF, programatically.

Add the name of the file that created the PDF to the PDF

add this snippet of code to the bottom of the script that you will publish with MATLAB's publish() function (or my MakePDF.m wrapper)

Quickly check if you have internet access 
ping -t 1 -q google.com | grep "0.0% packet loss" | wc -l

returns 1 for internet, 0 for no internet

One line frozen noise generator in MATLAB 
RandStream.setGlobalStream(RandStream('mt19937ar','Seed',1984));

sets the randsom stream to a particular state. (1984 because this is the most True state). Make sure you run this before every invocation of rand:

>> RandStream.setGlobalStream(RandStream('mt19937ar','Seed',1984)); 
>> rand(3)
