Definition in case of full column rank[edit]

The article says, "If all the columns are linearly independent, $\mathrm {spark} (A)$ is usually defined to be $m+1$ ". However, I'm questioning this claim. For instance, I wonder if it "should" instead be e.g. $n+1$ . The two supporting references do not seem relevant; the Princeton Companion to Applied Mathematics article does not consider the full-column-rank case, and the Industrial Mathematics and Complex Systems chapter does not apply.
