Week 2. NP

Introduction

Over the past week, laboratory work 3 and 4 were completed on the following topics:

1. Introduction to working with Octave
2. Systems of linear equations.

Lab №3

As a result of the work, I learned how to perform basic calculations and draw the simplest two-dimensional graphs using the Octave system for mathematical calculations.

The following tasks were completed:

• Perform simple operations.
• Perform operations with vectors.
• Calculate projector.
• Perform matrix operations.
• Build simple graphs.
• Build two graphs on one drawing.
• Plot $y = x^2sin(x)$.
• Compare cycles and operations with vectors

Lab №4

As a result of the work, I learned how to solve systems of linear equations using the Octave system for mathematical calculations.

The following tasks were completed:

• Solve SLAE using the Gauss Method
• Solve SLAE by applying left division
• Find LU decomposition
• Find LUP decomposition

Conclusions

Over the past week, I’ve learned how to do basic calculations and draw basic 2D graphs using the Octave math system. I also learned how to solve systems of linear equations using the Octave math system.
