WebfetchNext reads elements from F in order of completion. After fetchNext retrieves the outputs from the next unread Future object in the array F, MATLAB sets the Read property of that Future to true. If fetchNext reads an element from F that encounters an error, the function first sets the Read property of the Future element to true. WebThe fetchNext function returns the linear index of the future from its array. If instead, you need the subscript values of a multidimensional array, you can use the ind2sub function …
