Simulink Matlab独立可执行文件无法获取输出 [英] simulink matlab standalone executable unable to get output

问题描述

我有一个M脚本，该脚本通过GUI从用户那里获取参数值，然后使用更新后的参数值模拟simulink模型.我想将其转换为一个独立的exe文件，该文件无需Matlab& Simulink(即仅适用于Matlab Runtime Compiler).我正在使用32位MATLAB 2010b.

I have a M-script which takes the parameter values from user via a GUI and then simulates a simulink model with the updated parameter value. I want to convert it into a standalone exe file which can run without Matlab & Simulink (i.e. only with Matlab Runtime Compiler). I'm using MATLAB 2010b 32bit.

我的方法:
由于Matlab编译器无法转换 sim 函数，因此我首先使用Rapid Simulation目标将Simulink模型转换为exe文件，然后从matlab脚本中调用该exe文件.

My approach:
As the Matlab compiler cannot convert the sim function, I first converted my Simulink model to an exe-file using the Rapid Simulation target and then called the exe file from my matlab script.

[Gain1, Gain2]= InputDataGUI;
load Par.mat %contains parameter structure of the model
param_struct.parameters.values(1:2) = [Gain1 Gain2]; %update
save Par.mat param_struct;

!SimulinkModelName.exe -p Par.mat
save results.mat

此脚本可在Matlab中正常运行.最后，我使用 deploytool 将M文件以及所有其他必需文件打包到一个exe文件中.最终的exe文件运行GUI，并保存更新的Par.mat文件，但不提供模拟结果文件.我还尝试了 To File 块来保存结果.我认为该脚本无法运行仿真.

This script works in Matlab without errors. Finally I packaged the M-file along with all the other required files into an exe using the deploytool. This final exe-file runs the GUI and saves the updated Par.mat file but doesn't give the simulation result file. I have also tried the To File blocks for saving results. I think the script is unable to run the simulation.

我解决问题的方法正确吗?
我应该改为制作simulink mex文件吗?
预先感谢您的帮助.

Is my approach to the problem correct?
Should I make a simulink mex file instead?
Thank you in advance for any help.

推荐答案

您的一般方法是正确的.但是，可能还有几件事您还没有做完，

Your general approach is correct. However, there are possibly a couple of things that you haven't done,

1. 在Simulink中，应将模型设置为使用From File块作为输入，使用To File块作为输出
2. 在MATLAB中，需要设置代码以不仅为参数而且为输入信号生成.mat文件.
3. 运行模拟时，使用-p指定参数，使用-f指定输入文件(如果要覆盖模型本身中指定的文件)，使用-o指定输出文件的名称.您要写入数据(如果要覆盖模型本身中指定的数据).
4. 在您(已部署的)MATLAB代码中，您需要读取生成的.mat文件以存储输出，并对其进行适当处理(即绘制).

1. In Simulink, the model should be set up to use From File blocks for its inputs and To File blocks for its outputs
2. In MATLAB, the code needs to be set up to generate a .mat file not only for parameters, but also for the input signals.
3. When running the simulation use -p to specify parameters, -f to specify the input file (if you want to override the one specified in the model itself), and -o to specify the name of the output file you want the data written to (if you want to override the one specified in the model itself).
4. In your (deployed) MATLAB code you need to then read the .mat file generated to store the output, and process it (i.e. plot it) appropriately.
