    Matrix Analysis

    Can VB solve this problem?
    there is matrix 4x4 :

    1a + 2 b + 3 c + 4 d = 25
    3a + 2 b + 3 c + 8 d = 40
    5a + 27 b + 63 c + 4 d = 52
    7a + 8 b + 5 c + 4 d = 65

    can vb find a, b ,c and d?
    how?

    Can Vb work together with such as spss, minitab, etc to analyze this matriks? how?

    Yes, VB can find those results, if you program it to do so, lets say using Gauss-Jordan. The algorithm can be found in Google, of course, or in some Burden and Faires numerical analysis book (are quite basic, but they do solve this kind of problems).
    Remember VB is a programing language, not a specialized mathematics program. such as matlab or R, where you can also "program" some scripts, but you're actually not developing software.

    I think there should be a way to interact with them, but not that i can figure it out right now.

        VB cant find a,b,c,d by it-selft.
        You must find the algorithm for your-selft, VB can help you do complex calculation only.

          OK, Thanks.
          I want to ask again.
          So, VB can solve this problem itself, we must write the scripts alone, ok?
          Can't VB work gauss jordan itself?
          Example: i write in the script: A = GaussJordan M
          M is a matrix from VB work.

          Can VB do itself?

          And
          if no, can vb work with matlab, or others math software which can solve gaussjordan? So i can input the matrix in matlab(for example), and solve gaussjordan in matlab, and then come back to VB to show the result.

          O y, the input matrix is from VB.

            THANX A LOT.
            This URL give me an inspiration to work again.

              Yes, it's nice wikipedia replaces all the work you had to do in books before. I like that method very much, it's very fast and simple.

                As far as I know, Visual Basic can work with any product that provides an "automation " interface (Eg. MS Office products) or an API via DLL functions. It's not an area I'm very familiar with, though.
