This paper describes mathematical and software developments for a suite of programs for solving ordinary differential equations in Matlab.

The introduction of fast and efficient software for interval arithmetic, such as the MATLAB toolbox INTLAB, has resulted in the increased popularity of the use of interval analysis. We give an introduction to interval arithmetic and explain how it is implemented in the toolbox INTLAB. A tutorial is provided for those who wish to learn how to use INTLAB. We then focus on the interval versions of...

The demand in the technology requirements for diesel engines is growing keeping hybrid vehicles in mind. In future the diesel engine no longer drives the wheels directly; as a result the engine can be engaged at a limited number of operating points, thus, offering an opportunity to optimise the fuel efficiency and performance at those operating points. The extent to which this optimisation is p...

Many automated processes in digital photogrammetry such as relative orientation of a stereopair of aerial images or a derivation of a digital terrain model (DTM) are based on image matching. Several approaches to image matching have been developed. In this paper, attention is paid to area based matching. Using of MATLAB in procedures of finding parameters of exterior orientation of an aerial im...

Orthogonal frequency division multiplexing (OFDM) is a special case of multicarrier transmission and frequency division multiplexing, where a single data stream is transmitted over several lower rate subcarriers, placed orthogonal to each other. Today it is becoming the chosen modulation technique for wireless communications. It can provide large data rates with optimum bit error rate and enoug...

Matlab is a popular dynamic array-based language commonly used by students, scientists and engineers who appreciate the interactive development style, the rich set of array operators, the extensive builtin library, and the fact that they do not have to declare static types. Even though these users like to program in Matlab, their computations are often very computeintensive and are better suite...

abstractbackground: delivering the radiation dose to the target volume and minimizing the dose to normal tissues are the main objectives in radiotherapy. the aim of our study is to enhance the contrast of the portal image to increase the accuracy of delineation of the organs in the irradiation field.   methods: the software was written based on local enhancement of the pixel values in image mat...

This paper presents a MATLAB embedded package for continuous Petri nets called SimHPN . It offers a collection of tools devoted to simulation, analysis and synthesis of dynamical systems modeled by continuous Petri nets. Its embedding in the MATLAB environment provides the considerable advantage of creating powerful algebraic, statistical and graphical instruments exploiting the high quality ro...
