hobz Posted January 18, 2010 Share Posted January 18, 2010 I have constructed augmented matrix [math] \left[ \begin{array}{ccccccc|c} \frac{4}{5} & -1 & 0 & 0 & 0 & 0 & 0 & 1\\ 0 & \frac{4}{5} & -1 & 0 & 0 & 0 & 0 & 1\\ 0 & 0 & \frac{4}{5} & -1 & 0 & 0 & 0 & 1\\ 0 & 0 & 0 & \frac{4}{5} & -1 & 0 & 0 & 1\\ 0 & 0 & 0 & 0 & \frac{4}{5} & -1 & 0 & 1\\ 0 & 0 & 0 & 0 & 0 & \frac{1}{5} & -1 & 0\\ \end{array}\right] [/math] and I would like to find all solutions. How would I go about doing that? Link to comment Share on other sites More sharing options...

the tree Posted January 22, 2010 Share Posted January 22, 2010 I don't really see the issue here. Use Gaussian elimination and then back substitution as per normal. Link to comment Share on other sites More sharing options...
hobz Posted February 3, 2010 Author Share Posted February 3, 2010 Hmm.. Just thought there were some way like with overdetermined systems. Link to comment Share on other sites More sharing options...
