The workshop provided a forum through which mathematicians and statisticians may be better informed of the latest developments and newest techniques in linear algebra and matrix theory and may exchange ideas with researchers from a wide variety of countries.
As well as range of invited speakers we strengthened the interactions between participants by organizing several special sessions in various of areas. We also invited participants from all areas of mathematics to submit their research articles in the sessions of contributory talks.
The theme of the workshop targeted on the theory and applications using matrices in different branches of science like: big data analytics, machine learning, computer and information science, biology, physics, economics, engineering, mathematics and statistics.
