If I write a function in a .m file and try to run it by pressing the "run" button, will the function just be set in the environment or also run, maybe without arguments?
If the function does not take any arguments, then it will simply be executed. If the function does take arguments, and you try to run it via the GUI, you should be prompted to enter a set of default arguments that should be used. These arguments will be used if you ever run the script in the future.
This is described in Matlab's documentation here.
There are two types of mfiles (files with .m extension) in Matlab:
Scripts and Functions. (See Scripts vs. Functions)
See Calling a function for how to use a function programmatically.

I want to do something like $foo | .\bar.ps1, and handle $foo inside bar.ps1. What's the minimal example of bar.ps1 in which I can access the value of $foo?
Edit:
The question has been closed, but I have found the answer: write in the file as if it's a function, but just strip function {} keyword, just put what you would put inside the {}. If you don't have a process{} block, use $input to access the piped value. If you have a process{} block, use $PSItem.
It's worth noting that $input can only be accessed once, so save it to a variable first.

function A(B,C)
load d.mat
my code
end
Is there a way that I can use d.mat file without load/import it. Or is there a way that do not need to load/import d.mat file every time I run function A.
You can pass the variable/content of d.mat as an extra parameter to the function A.

I have doudt, Is scala interpreter(REPL) compiles the command and run by the JVM like how the scalac compiles a program ?
Simply Does it work like any other normal interpreter ?
The standard Scala interpreter, as experienced in the REPL for example, is a variant of the compiler that takes input, wraps it in an invisible object and compiles it on the fly (like any other regular Scala program), then runs the body of that virtual object.
The Scala Meta project might offer a different approach of a more direct interpretation without going through full-to-byte-code compilation.

I want to write some notes in the draft of a LaTeX document, and at a later point I want to compile the document without them. I saw someone doing something like the following (but I forgot what he did). Write notes as {\scriptsize some_text}, and in the end replace all {\scriptsize ...} with {} with a \newcommand. But I can't figure out how to write a \newcommand to replace all {\scriptsize some_text} occurrences by empty strings. I can then just comment or uncomment the \newcommand line.
Declare in the beginning of your file
\somevariabletrue
%\somevariablefalse
so you can quickly uncomment one and comment second, and in the later part of your code:
\ifsomevariable
...
\else
...
\fi

is there any pgp key dumping program like http://www.pgpdump.net/ that also shows the MPI values as well as the other information? the linked website's program will print out ... for the long MPI, which is perfectly logical, but I want to see the values since my program is for some reason getting all but one part right (reading an elgamal public key), and its messing with everything that comes afterwards. i want to see where im off by a few bits
gpg --list-packets --debug-all should show MPI values.
pgpdump.net links to the source code of pgpdump. Perhaps you could find the part where ... is written and change it in a local copy of the program.
