说明：  matlab中关于数值分析的一个matlab源程序(numerical analysis matlab on a matlab source)

Goal of the project was to implement numerical methods for solving systems of nonlinear algebraic equations using MATLAB software. As in previous assignment first of all I need to research for functions, which would be helpful during evaluation of each task, later on I was able to implement and test numerical algorithms for solving given problems. Each student got three different equations to solve, and create another one with use of them for finding its zero place with various methods. Each method, result, comment and conclusion is placed in this report. At the end of the report one can find my MATLAB programs, and all references which were used as a help for me during evaluation.
