Hi! I have some questions about matrices and solving linear systems of equations. These issues arose out of my using Sage for examples in my Linear Optimization class (it's great for demonstrating how the simplex algorithm works!) and for research I'm doing involving finite fields.
If I have a matrix A defined over some finite field, and a vector b over the same finite field, what's the easiest way to solve the equation Ax=b? Is there any easy way to augment A with b as an extra column? Is there an easy way to insert a row or column? Is there an easy way to delete a row or column? The same questions apply for matrices over the rationals. The functions stack() and insert_row() are pretty useful, but they seem to be only defined for matrices over the integers. Thanks for any help, Stephen --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
