What Is The Purpose Of Matrix Algebra?

  1. Oct 9, 2009 #1
    Well I'm going to be taking Matrix Algebra next semester, and I have no clue what it's for. Wikipedia wasn't too enlightening. What is the purpose of matrix algebra, and what is is commonly used for?

    Solving systems of equations.

    That's one possibility. More generally, matrices allow you to work with a whole lot of things at once. (As, for example, a whole lot of equations.) In my opinion, the most important property of matrices is that they can be used to represent linear transformation on a vector space. But if you course is specifically titled "Matrix Algebra" rather than "Linear Algebra" you probably won't be working with that.

    I mostly use them to solve systems of equations. They're extremely important for computer graphics, to give one application example.

    Yeah, the course is just called "Matrix Algebra for Engineers".
