Many options and further matrix operations are available. Both Sparse BLAS and the own interfaces are supported (C/C++, Fortran). You can also use librsb transparently in a Matlab-style fashion via the GNU Octave `sparsersb` package and command, or in Python via the `pyrsb.rsb_matrix` class inspired by `scipy.sparse` classes. This release improves SpMM operation performance considerably; it introduces a new, class-based C++ interface; many minor improvements listed on http://librsb.sourceforge.net/NEWS.TXT The source code of librsb is LGPLv3 licensed.

Lespinats, B. Colange and DD (2022). Nonlinear Dimensionality Reduction Techniques: A Data Structure Preservation Approach. Springer, Cham, 12 b/w illustrations, 88 illustrations in color. Hardcover ISBN: 978-3- 030-81025-2, Softcover ISBN: 978-3-030-81028-3. DOI: https://doi.org/10.1007/978-3-030-81026-9 This book proposes tools for analysis of multidimensional and metric data, by establishing a state-of-the-art of the existing solutions and developing new ones. It mainly focuses on the visual exploration of these data by a human analyst, relying on a 2D or 3D scatter plot display obtained through Dimensionality Reduction (DR). Performing the diagnosis of an energy system requires identifying relations between observed monitoring variables and the associated internal state of the system. DR, which allows representing visually a multidimensional dataset, constitutes a promising tool to help domain experts to analyze these relations. This book reviews existing techniques for visual data exploration and dimensionality reduction and proposes new solutions to challenges in that field. In order to perform the diagnosis of energy systems, domain experts need to establish relations between the possible states of a given system and the measurement of a set of monitoring variables. Classical dimensionality reduction techniques such as tSNE and Isomap are presented, as well as the new unsupervised technique ASKI and the supervised methods ClassNeRV and ClassJSE. A new approach, MING for local map quality evaluation, is also introduced. These methods are then applied to the representation of expert-designed fault indicators for smart-buildings, I-V curves for photovoltaic systems, and acoustic signals for Li-ion batteries.

In the context of its research in the field of applied mathematics, WIAS develops research software and uses and generates research data. The research software has different levels of complexity - from publication-accompanying scripts to internationally leading open source software and codes in industrial projects. An important part of the research results of WIAS is "formulated" in research software and data. As an integral part of the research process, this software and data are subject to the requirements for research as a whole. These include the rules of Good Scientific Practice and the resulting "FAIR" principles (Findable, Accessible, Interoperable, Reusable). To support the scientific projects of WIAS in this area, WIAS is looking for an Research Software Engineer with interest in research data management (m/f/d), (identification number 22/01). In the short term, the work tasks consist primarily of setting up and structuring services (continuous integration, issue handling, release management archiving, etc.) and reproducible environments (predefined software environments) for sustainable, quality-assured development of research software on the basis of a locally operated Gitlab instance, as well as supporting scientists in their use. The support includes, among other things, training, hands-on consultation, and the production of best practice documents. In the medium and long term, in addition to the further development of the structures and services described above, the focus is on the support of software projects including open source software developed at WIAS or with the collaboration of WIAS members. The focus is on consulting on scientific software libraries and documentation tools, on the implementation of FAIR principles in software development and in research data management. The structured on-boarding/off-boarding of scientists who start their work at WIAS or leave the institute is to be supported, as well as the securing of their results available in the form of software and research data. The same applies to third-party funded projects.
