Homework Statement
Describe the possible echelon forms of the standard matrix for the linear transformation T.
T: |R3 --> |R4 is one to one.
The Attempt at a Solution
T(x)=Ax. Right? So A must be the standard matrix.
I got this: A =
| £ * * |
| 0 £ * |
| 0 0 £ |
| ? ? ? |
Where £ represents a pivot position, and * any random number.
The only problem is that I have no idea what to put in the lowest row.. Can you guys help?
