Empty arrays follow array concatenation behavior. For example, create an empty array ofdoubleand concatenate it to create a second array. A = double.empty(0,5); B = [A A] B = 0×10 empty double matrix Version H
Array Empty array. Throws matlab::OutOfMemoryException Unable to allocate the array. createBuffer template <typename T> buffer_ptr_t<T> createBuffer(size_t numberOfElements) Description Creates an uninitialized buffer to pass to thecreateArrayFromBuffermethod. ...

You also can use the{}operator to create an empty 0-by-0 cell array. C2 = {} C2 = 0×0 empty cell array When you want to add values to a cell array over time or in a loop, first create an empty array using thecellfunction. This approach preallocates memory for the cell array...
Create an array of zeros that is the same size as an existing array. Get A = [1 4; 2 5; 3 6]; sz = size(A); X = zeros(sz) X = 3×2 0 0 0 0 0 0 It is a common pattern to combine the previous two lines of code into a single line: Get X = zeros(size(A...
Create two arrays. Get A = ones(2,3); B = rand(3,4,5); If size(A) and size(B) are the same, concatenate the arrays; otherwise, display a warning and return an empty array. Get if isequal(size(A),size(B)) C = [A; B]; else disp('A and B are not the same size....
