SUMMARY

The discussion focuses on solving a system of linear equations symbolically in MATLAB, specifically the equations 3x + 4y + 5z = 2, 2x - 3y + 7z = -1, and x - 6y + z = 3. The user struggled with using the MATLAB functions 'linsolve' and 'solve' for this task and sought clarification on matrix multiplication. The solution was found by following a provided link that outlines the necessary steps for using MATLAB effectively.

PREREQUISITES
  • Familiarity with MATLAB syntax and functions
  • Understanding of symbolic mathematics in MATLAB

The Attempt at a Solution


This assignment was given with about 20 different basic MATLAB questions and this is really the only one that I cannot get. I really don't even know where to start. I tried the online help copy and pasting different types of functions such as linsolve and solve Y but I just cannot get it to work. I also need help multiplying in matrix form. Can anyone please explain to me how to go about this. Thanks
