WebbYou need Rank (A)< the full rank. This is just the definition of a rank deficient matrix. Since column rank = row rank, a non square matrix (2x3, for example) should return a rank ≤ 2? Its rank will be at most 2. The rank could also be $0$ or $1$. Here are examples: Rank Zero: \begin {bmatrix} 0 & 0 & 0\\ 0 & 0 & 0 \end {bmatrix} WebbTo say that a non-square matrix is full rank is to usually mean that the row rank and column rank are as high as possible. In the example in the question there are three …
