在Simulink中,您可以使用 MATLAB 函数块来实现 `persistent` 变量。以下是一个简单的示例: 1. 打开Simulink模型。 2. 在模型中添加一个 MATLAB 函数块。 3. 在 MATLAB 函数块中使用 `persistent` 关键字定义变量。 function y = myMATLABFunction(u) % 定义 persistent 变量 persistent myPersistentVariable; %...
To make sure that the persistent variables inside the MATLAB Function block map to a register on the target FPGA device, update the persistent variable at the end of the MATLAB® code inside the MATLAB Function block. Do not update the persistent variable before its value is re...
在Simulink模型中添加matlabfunction函数块的方法如下：1.打开Simulink模型。2.在工具栏上选择”Library Browser”。3.在Library Browser窗口中，选择”MATLAB Function”库。4.将matlabfunction函数块拖动到模型窗口。在matlabfunction函数块内编写MATLAB代码的步骤如下：5.双击matlabfunction函数块打开编辑器。6.在编辑器中...
MATLAB structures enable you to bundle data of different sizes and types into a single variable. You can create a MATLAB structure to:Store related data in a local or persistent variable of a MATLAB function Read from or write to a local Stateflow bus Interface with a Simulink bus signal ...
After Simulink® calculates the estimated location of the object, theVisualizingblock plots the actual and estimated locations of the object by using the MATLABplotfunction. functionplot_me(y,z) persistenthifisempty(h) h = figure; hold;end ...

A function defined in a Simulink Function block can be called from a Function Caller block, a Chart (Stateflow), a MATLAB Function block, a MATLAB System block, or an S-Function block. For more information, see Call a Simulink Function from a Model. Model Considerations When using a ...
persistent last_best Creates the persistent variable last_best, the best objective function value in the previous generation. Persistent variables are preserved over multiple calls to the plot function. set(gca,'Yscale','log') Sets up the plot before the algorithm starts. best = min(optimvalues...
