Here's a method for inverting matrices using row reduction, which I think is what you are after: Let A be an n × n matrix. Let B be the n × 2 n matrix obtained by placing the n × n identity matrix to the right of A : B = ( A I n). Now, perform row reduction on this matrix until the left half is the identity matrix (or has a row of zeros).
