Course aims:

The general aim related to this course consists in getting knowledge which helps the students to use the mathematical concepts together with a specific software to model phenomena from various fields as medicine, physics, chemistry, economy, sociology etc..
A specific aim is related to the use of Matlab and Excel software to model various reality-based problems with mathematical tools.
Besides the knowledge of basics mathematical modeling aided by software products, the course is focused also on the development of an open minded approach of the interdisciplinary matter.
