matlab mep
mep creates epochs (0|1) in a logical array according to a list of indices (begin:end). more>> matlab mep is a program that helps with creating epochs (0|1) in a logical array according to a list of indices (begin:end).
Creates - completely vectorized - a logical array/vector with epochs/intervals set to according to a list of indices of the form:
begin = [b1 b2 ... bN]
end = [e1 e2 ... eN]
where s and s may overlap or be included within each other.
lvec=[b1:e1 b2:e2 ... bN:eN]
itself can be used to retrieve/assign values from a numerical construct, eg,
vec(1,2,lvec)=nan;
help mep
vix = mep(v,ixb,ixe)
vix = mep(v,[ixb;ixe])
to create epochs
returns in VIX a array with epochs set to
true: ixb(1)->ixe(1) ... ixb(N)->ixe(N)
false: otherwise
correctly handles epoch overlaps/inclusions/reversals
v: vector (to size VIX, is not changed)
ixb: list of indices BEGIN epoch
ixe: list of indices END epoch

TCP/IP Communications in Matlab
This is a simple TCP/IP communications application written in Matlab more>>
TCP/IP Communications in Matlab is considered as a simple yet useful TCP/IP communications application written in Matlab. The script relies in MATLABs ability to call Java code snippets and make use of its TCP/IP implementation.
One Matlab session can communicate with another Matlab session (on the same machine or over the network) or it can communicate with a completely different program (again, on the same machine or over the network).
Requirements:
- MATLAB 7.8 or higher.

DataTable is a useful tool which can store data in a table format that is easily expandable, manipulatable and that supports printing in a variety of formats (plain text, Latex, HTML, Wiki; new printing formats can be added without changing any code). The format of numeric table contents (e.g. number of displayed digits) and the alignment of text and numbers can be changed for each column individually.
To use, extract zip-archive and add the extracted folder ('datatablepackage') to your matlab path.
Requirements: the new object-oriented programming in MATLAB 7.6 (R2008a) or higher

image2data will makes you pleasant with its MATLAB script that can convert a bitmap image to numerical data.
Data can be extracted from an image using a color bitmap and a horizontal colorbar, with all color levels ranging from left to right. The colorbar is used to generate an equivalent set of gray levels and the RGB components are properly converted to gray levels. Afterwards gray values are properly scaled to the interval of numerical values specified by the user. This tool can be used to recover numerical data from digital images when the original data is not available.

FACTORIALM provides you with an excellent and very useful extension of factorial.m in Matlab R13 which is designed for matrices. It is inspired by a post on CSSM. F = FACTORIALM(M) returns the factorial for all integers of the matrix M. So,F(i) is the product of all integers from 1 to M(i), i.e. prod(1:M(i)). F has the same size as M. NaNs and Infs in M will yield NaNs in F.
factorialm([1 6 0 ; NaN 4 -Inf])
will return : 1 720 1
NaN 24 NaN

Fractions Toolbox is such a great and useful MATLAB toolbox that will help to create and manipulate fractions (K+N/D) using exact arithmetic.
A powerful feature of the toolbox is that the numerator and denominator can theoretically be any data types that accept the standard arithmetic and comparison operations as well as gcd and mod.
If there exists a suitably defined polynomial object, this toolbox could be used to perform partial fraction and series expansions of rational functions.
