# Mathematical modelling

Problem solving using Matlab package: introduction into Matlab package, manipulation of matrices and arrays, graphics, writing scripts and functions, overview of basic Matlab toolboxes (numerical solution of sytems of linear and nonlinear equations, optimization, numerical integration and numerical solution of ordinary differential equations, sparse matrices), Matlab as a tool for solving some simple problems.

Optimization: solving problems based on constrained optimization (discrete catenary, symmetric discrete catenary, symmetric discrete catenary having an odd or even number of segments, truss oscillation).

Calculus of variations: brachistochrone problem, catenary, minimal rotational surface.

Statistics: χ2 test (chi square test), statistical simulations, simulation of games.

A student is faced with bacis concepts of problem solving, particularly those arising from mathematical modelling. She or he is able to use matlab as a tool and learns how to evaluate obtained results. Some deeper skills are obtained in solving problems based on finding extrema, calculus or variations and statistical simulations.

Knowledge and understanding: Basic programming in Matlab. Capability of solving some simple problems of mathematical modelling using Matlab. Understandig of theoretical fundamentals to solve problems involving scalar field extrema, capability of solving problems in calculus of variations and skills in implementation of statistical simulations.

Application: Using Matlab package as a tool for solving some simple problems arising from mathematical models.

Reflection: Understanding theory through practical experiments (computer programme coding).

Transferable skills: Capability of using computer software, particularly Matlab package. Understanding of basic approaches for solving mathematical problems and evaluation of results. The subject upgrades the knowledge obtained from several other subjects of mathematical studies (analysis, algebra, programming,…)
