| I think we're both ok on that score! |
| Thanks! That works. Based on your explanation, I don't need the Thread, right? It works without it. So is it actually internally doing some iteration over values of x1, x2, and x3 in their given ranges; each time plugging those values into A.{x1,... |
| Thanks, Daniel. The LU decomposition is definitely way beyond my students. These are students who are just starting out in linear algebra. Even augmenting with an identity matrix is more than I want to get into in the beginning. Thanks for the... |
| I'm aware of how to align a system of equations on the = sign (or other single alignment point), but I'd like to align a system at multiple points so that each variable stays in its own "column" so to speak. This is especially an issue if some... |
| Thanks! I know about the Maximize function. Really wanted LinearProgramming to work for either max or min! |
| I'm new to Mathematica and am teaching an applied linear algebra course. We start off doing elementary row operations on an augmented matrix to solve a system of equations. I know about the RowReduce command, but that does all the row operations at... |
