The research aim is to highlight Methodical aspects of teaching discipline “Work in MATLAB package” for the students of specialty 121 Software Engineering. The research object is the construction process of the complex surfaces’ charts, presented by the function of two variables. The research subject is the use of the package possibilities (the grid generation; the calculation of values in the grid node; the construction of a surface chart with the use of the linear and quadratic spline). The organization of the discipline’s studying foresees mastering of the main methods, ways and means of the data obtaining, preservation, processing; ability to use the packages of the applied software; introduction to the solvation of the linear equations’ systems with the usage of different methods; introduction to the high-level graphics, polynomials and interpolation, splines and forms of their realization. The analysis, the generalization and systematization of the investigations, concerning the usage of MATLAB package’s possibilities in the process of the Master qualification work’s preparation on speciality 121 – Software Engineering are made in the paper.
