Sammanfattning 
MATLAB (by MathWorks) is a widely used program for algorithm
development in image analysis and many other disciplines. In MATLAB,
matrix and vector processing operations are optimized and there are
many builtin functions which are fast. However, in some cases it is
hard to state a problem on vector form and use the builtin functions,
which sometimes make the implementation of the algorithm
unefficient. Especially this is a problem if forloops are used. In such
cases other solutions than pure MATLAB solutions using mfiles are
beneficial.
MATLAB provides an interface to external routines in C and Fortran through
MEXfiles. In this seminar I will give an introduction to MATLAB
MEXfiles using C, and discuss how MEXfiles can be
applied to get faster implementations in an easy way while maintaing
the benefits of using MATLAB, like easy visualization of the result
and access to many basic functions useful in algorithm development.
