全相位陷波器是全相位数字信号处理体系中一个很有特色的技术，在通信、军事等抗强干扰场合中应用及其广泛，因而研究全相位陷波器并仿真建模实现其滤波功能，具有很高的意义。(All-phase notch filter is a very distinctive technique in the all-phase of digital signal processing system. In communications，military and such resistance interference are widely used. Therefore, it is of high significance to the study of All-phase notch filter and simulate the modeling to realize the filter function)

Goal of the project was to implement numerical methods for solving systems of linear algebraic equations using MATLAB software. First of all I had to learn the structures of programming in MATLAB, later on I was able to implement and test numerical algorithms for solving given problems. All results, comments and conclusion are placed in this report. At the end of the report one can find my MATLAB programs, and sources which were used as a help for me during evaluation. Each task is presented under separated heading, with its full description, problem discussion, my approach for solving it and explanation.
