Modern software systems are increasingly dependent on third-party libraries. It is widely recognized that using mature and well-tested third-party libraries can improve developers’ productivity, reduce time-to-market, and produce more reliable software. Today’s open-source repositories provide a wide range of libraries that can be freely downloaded and used. However, as software libraries are d...

In 5, 6], we presented algorithm RGEQR3, a purely recur-sive formulation of the QR factorization. Using recursion leads us to a natural way to choose the k-way aggregating Householder transform of Schreiber and Van Loan 10]. RGEQR3 is a performance critical sub-routine for the main (hybrid recursive) routine RGEQRF for QR fac-torization of a general m n matrix. This contribution presents a new ...

We present our project to develop a software library of basic tools and data structures for string processing. Our goal is to provide an environment for testing new algorithms as well as for prototyping. The library has a natural hierarchy comprising basic objects such as the alphabet and strings, data structures to manipulate these objects, and powerful algorithmic techniques driving these dat...

We present an implementation of an EC cryptographic library targeting three main objectives: portability, modularity, and ease of use. Our goal is to provide a fully-equipped library of portable source code with clearly separated modules that allows for easy development of EC cryptographic protocols, and which can be readily tailored to suit different requirements and user needs. We discuss sev...

If the role of software libraries is to communicate information about software artefacts between software engineers, it is vital that the information be stored in such a manner as to be readily understandable. The designs of existing software libraries present several cognitive impediments to a software engineer, hindering the understanding of library organisation and content. In this paper, a ...

Many automated programming environments construct software by integrating predefined components from a software library. A fundamental challenge in this process is to match the programmer’s specified requirements against the stated capabilities of the components. We explain how the chances of successfully achieving a match can be increased by taking the program context surrounding each requirem...

We describe the model reduction software developed recently for the control and systems library SLICOT. Besides a powerful collection of Fortran 77 routines implementing the last algorithmic developments for several well-known balancing related methods, we also describe model reduction tools developed to facilitate the usage of SLICOT routines in user friendly environments like Matlab or Scilab...
