1. The problem statement, all variables and given/known data Prove or disprove the following statement: If A is a singular matrix (detA=0) the it's similar to a matrix with a row of zeros. 2. Relevant equations 3. The attempt at a solution I know that A has an e-value 0 which means that it's similar to a matrix that has a column of zeros but how do I relate that to the rows? Thanks.
