Since MATLAB initializes a persistent variable to an empty matrix ([]), typically functions check to see if a persistent variable is empty, and, if so, initialize it. functionmyFun()persistentnifisempty(n) n = 0
If you want to use the point tracker as a persistent variable, you must call initialize only during creation. If you call initialize in a loop, the previous state is lost and therefore, the tracker cannot maintain tracking. exampleExamples collapse all Track a Face in Scene Copy Code Copy ...
Map Persistent Variables to RAM You can use persistent variables to model registers. For example, to preserve the state between invocations of your MATLAB® algorithm, use persistent variables. Before you use a persistent variable, you must initialize it with a statement that specifies its size ...
I'm thinking: use the init flag to initialize a persistent variable to []; use the calls with no flags to append to the persistent; use the done flag to transfer data out of the persistent (possibly by setting a global.) 댓글 수: 2 ...

图中的节点(Nodes)一般用来表示施加的数学操作,但也可以表示数据输入(feed in)的起点/输出(push out)的终点,或者是读取/写入持久变量(persistent variable)的终点;线(edges)则表示在节点间相互联系的多维数据数组,即张量(tensor),训练模型时,tensor会不断的从数据流图中的一个节点flow到另一节点, 这就是 TensorFl...
