Create a random 4-D array and return its size. Get A = rand(2,3,4,5); sz = size(A) sz = 1×4 2 3 4 5 Query the length of the second dimension of A. Get szdim2 = size(A,2) szdim2 = 3 Query the length of the
Array size collapse all in page Syntax sz = size(A) szdim = size(A,dim) szdim = size(A,dim1,dim2,...,dimN) [sz1,...,szN] = size(___) Description sz= size(A)returns a row vector whose elements are the lengths of the corresponding dimensions ofA. For example, ifAis a 3-...
