SOLUTION: You have been performing Gaussian Elimination, and now you have all of the lower triangle elements with value 0. What are you ready to do? I think the answer is c, but I want to m

Question 156056: You have been performing Gaussian Elimination, and now you have all of the lower
triangle elements with value 0. What are you ready to do? I think the answer is c, but I want to make sure

a. Nothing, you are done with Gaussian Elimination
b. Start with forwards elimination
c. Start backwards elimination
d. Start over; you are supposed to have all zeroes in the upper triangle

You are correct. You want to end up with a matrix with a diagonal of 1's where every other element (except for the far right column) is zero.


Note: It's not always possible to obtain this since you may have no solutions or an infinite number of solutions.
