You probably want: (shape M) ;; returns a vector [4 6] for a 4x6 Matrix
Though you can also access the individual dimension sizes as follows, which is sometimes useful: (dimension-count M 0) ;; returns 4 as the count of the first dimension (dimension-count M 1) ;; returns 6 as the count of the second dimension More generally, check out the clojure.core.matrix namespace for all the public API functions.
