Help Center Help Center. For example, if A is a 3-by-4 matrix, then size A returns the vector [3 4]. If A is a table or timetable, then size A returns a two-element row vector consisting of the number of rows and the number of table variables. You can also specify dim as a vector of positive integers to query multiple dimension lengths at a time. For example, size A,[2 3] returns the lengths of the second and third dimensions of A in the 1-by-2 row vector szdim. You can query multiple dimension lengths at a time by specifying a vector dimension argument. For example, find the lengths of the first and third dimensions of A. Find the size of the table.
