This paper discusses how the aspects unique to the Java programming language can be combined with complementary and unique aspects of other languages such as C and Fortran. This combining of the strong features of Java, such as portability and platform independence, with packages and legacy codes written in traditional languages such as C and Fortran results in a program blend which exhibits po...

Many beginners are far from being able to overcome the difficulties of the elementary programming study based on such languages as Pascal, Basic, C or Fortran. The success of the Logo "turtle graphics" ilas stimulated the development of the new approach towards the elementary programming teaching. This "mini-language" approach is discussed briefly in the paper. As an example of mini-language we...

The resource constrained shortest path problem is an NP-hard problem for which many ingenious algorithms have been developed. These algorithms are usually implemented in FORTRAN or another imperative programming language. We have implemented some of the simpler algorithms in a lazy functional language. Beneets accrue in the software engineering of the implementations. Our implementations have b...

We describe favorable experience with automatic differentiation of mathematical programming problems expressed in AMPL, a modeling language for mathematical programming. Nonlinear expressions are translated to loop-free code, which makes analytically correct gradients and Jacobians particularly easy to compute — static storage allocation suffices. The nonlinear expressions may either be interpr...

In recent years, ne,\x/ insights into the nature of programming languages have been obtained from the comparative study of natural and programming languages. These studies reveal that programming languages are deficient in their ability to adapt both to new requirements and new means for communicating thoughts. A means of alleviating these difficulties, through a dynamic, structured expansion o...

This paper describes a study of the use of data-parallel languages such as Fortran D or High Performance Fortran (HPF) and their compilation systems for existing large scienti c applications. The central question addressed in this study is: Do such languages allow the expression of the parallelism available in the applications so that the underlying compilation systems are able to generate e ci...

Parsing a Spice netlist is the first step of all circuit simulation programs. This part is usually done by low-level coding techniques in C or Fortran language. The aim of this paper is to show the usefulness of functional programming techniques to the needs of scientific computing. Key-Words: Spice Netlist, Parsing, Scanning, Functional Language.

Fortran is still a very dominant language for scientific computations. However it lacks modern language features like strong typing, object orientation, and other design features of modern programming languages. Therefore, among scientists there is an increasing interest in object oriented languages like Java. In this paper, we will discuss a number of prospects and problems in Java for scienti...

In this paper, we describe our implementation of a primal-dual infeasible-interior-point algorithm for large-scale linear programming under the MATLAB 1 environment. The resulting software is called LIPSOL { Linear-programming Interior-Point SOLvers. LIPSOL is designed to take the advantages of MATLAB's sparse-matrix functions and external interface facilities, and of existing Fortran sparse Ch...
