WebWhat does the abbreviation DET stand for? Meaning: detached; detachment. WebI wrote an answer to this question based on determinants, but subsequently deleted it because the OP is interested in non-square matrices, which effectively blocks the use of determinants and thereby undermined the entire answer.
