Services for Numerical Calculation

Many discussions about algorithms in the specialty literature on the web omit important details, which can only be uncovered by encoding or suitable by reading the code. We also need the real code for objects oriented programming, found in numerical library in Java for scientists and engineers book. An orientation of these solutions is for scientific explanations which base on the numerical calculation, beginning with elementary structures, up to complicated ones, as the integration of the ordinary deferential equations. The purpose of the present paper is the analysis of the advantage of the Web interface and the simplest way of its facilities. To support my work, I use the book numerical library in Java for Scientists and Engineers; with the mention that I do not re implement them, but I only use those which are already implemented. The passing from an interface of the command line type, with the user to an interface based on Web services represents a great advantage for it allows the combining and the reusage of some routines, previously defined.
