I looked up on scipy manual,
https://docs.scipy.org/doc/scipy/reference/genindex.html#G
but don't see this 'gearf' function anywhere.
Does any one recognize it and can provide documentation for it?
Perhaps it is not just geqrf but dgeqrf or sgeqrf or cgeqrf or zgeqrf?
Look at the Scipy examples here to see how they use get_lapack_funcs() without specifying the type.
If you want to access directly to the LAPACK routine then it is accesible via
scipy.linalg.lapack.sgeqtrf
scipy.linalg.lapack.dgeqtrf
scipy.linalg.lapack.cgeqtrf
scipy.linalg.lapack.zgeqtrf
or you can use what Antimony suggested.
But this is already wrapped via scipy.linalg.qr. If you set pivoting to True, ?geqr3 is used and otherwise ?geqrf is used in the background.

I have a code in MATLAB that I need to run once to get some quick reference results. This code uses dsearch(), and I relized that this function has become deprecated and has been substituted by dsearchn(). I tried to follow some suggestions to make it work but I didn't succeed (it's my absolute first time with MATLAB) and I just need to run this code once to get some numbers. Which MATLAB versione should I install to make it work?
dsearch was removed in MATLAB R2012a, therefore you may use any version of MATLAB before R2012a.
If you have an active MathWorks account, you may access the documentation archive here.
According to MathWork's release notes, this function started printing a warning on release 2010a. So you should be fine either using it or a previous version.
I'm interested in using the qlot library from inside of a Lisp image to manage multiple local instances of quicklisp.
There doesn't seem to be any documentation on how to use it, except through a non-Lisp CLI interface, and the obvious
(qlot:with-local-quicklisp (#P"/a/path/here/") (qlot:install :skippy))
or
(qlot:with-local-quicklisp (#P"/a/path/here/") (qlot:quickload :skippy))
give me
Component "skippy" not found
[Condition of type ASDF/FIND-SYSTEM:MISSING-COMPONENT]
What I'm looking for is a way to install a particular library by name. Basically, exactly how one would use ql:quickload, but targeting a specific, local directory instead of ~/quicklisp. What am I doing wrong?
It looks like the intent is to modify dynamically scoped variables in a way that makes using ql:quickload directly possible.
So
(qlot:with-local-quicklisp (#P"/a/path/to/some/quicklisp/")
(qlot/util:with-package-functions :ql (quickload)
(quickload :skippy)))
will result in skippy being installed in the quicklisp instance at #P"/a/path/to/some/quicklisp/" instead of the default location.
This leaves me a bit perplexed as to what qlot:quickload is for; its describe output doesn't shed additional light.
Is there an equivalent function in FreeMat? I can't seem to find one and the documentation is poorly organised.
Any recommendations for work-arounds?
I am not sure if that helps, but I am not using this function in Matlab either. I always organise my objects in a list that is either stored in a global workspace or passed around other to objects.
So what you could do is create an Object like a list that has a search and add function. Put it in global scope and make it a singleton (I know, friends don't let friends write singletons). This way you can find all you add to this list easily.

I think the findobj() function in MATLAB does someting similar.
I'm using Eclipse with the OcaIDE-Plugin to write my ocaml-project.
I have written several ocaml-functions that I want to document (comment, return values and params).
I've created my documentation in the .ml-files like described in this link: http://caml.inria.fr/pub/docs/manual-ocaml/ocamldoc.html
Here is an example of one function:
(** sorting tuples where first element is key *)
let my_comp x y = (*Some code*)
Unfortunately, my comments don't show up, when I press F2 at one of the functions, it only shows the name and the file it is contained.
When writing comments in an mli-file, it works as expected, but i also want to document "private" functions that are not accessible from the outside. Can I define functions in the mli, that are NOT accessible from the outside, just for the documentation?
How can I make Eclipse to show my documention?
Well, as you said, you would like to show the documentation but not export the function out of the module. That, sadly, won't work.
I guess OcaIDE can be considered as incomplete but it doesn't look like it's something people care about (I don't know a single person working on OcaIDE). If you like having autocompletion etc, maybe try to program with emacs and install merlin (look, I found the perfect post for you : here)
As for the suggestion of defining a function in the mli not accessible from the outside, it's completely opposed to why mli files are created, so don't expect that to be possible. ;-)
I hoped I've been able to help you.
Is there a way to know the functions involved in a demo on Matlab ? I mean starting from a function/Script demo can I have a tree of all involved files/functions on the current demo that has been called by the demo.
Look into depfun.
Quote from the documentation -
depfun Locate dependent functions of program file.
TRACE_LIST = depfun(FUN) returns a cell array of files of the dependent
functions of FUN.
An alternative, possibly more interactive, way to have a look at what has been used is to use the profiler:
profile on -history
% now run some code or function
profile off
profile viewer
not really what it was designed for but could be used in this way
