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;endn = n+1;end
initialize(pointTracker,points,I)initializes points to track and sets the initial video frame. The function sets theM-by-2pointsarray of [x y] coordinates with the points to track, and sets the initial video frame,I. If you want to use the point tracker as a persistent variable, you must...
To define persistent variables that are structures, declare the variable as persistent in the function code. See persistent and Initialize Persistent Variables in MATLAB Functions. For example, to declare the persistent variable, myVar, enter: persistent myVar Then define the variable structure in the...
For more information, seeInitialize Persistent Variables in MATLAB Functions. You also cannot call custom code functions inMATLAB Functionblocks because it is not possible to enforce that the outputs of custom code functions depend only on the current state. Calling a custom code function in aMATLAB...
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...
