[技术]FRED如何调用Matlab [复制链接]

简介：FRED作为COM组件可以实现与Excel、VB、Matlab等调用来完成庞大的计算任务或画图，本文的目的是通过运行一个案例来实现与Matlab的相互调用，在此我们需要借助脚本来完成，此脚本为视为通用型脚本。 k^3>Y%^1  
[L3=x;U  
配置：在执行调用之前，我们需要在Matlab命令行窗口输入如下命令： 'nzg6^I7g  
enableservice('AutomationServer', true) I5k$H$  
enableservice('AutomationServer') t6bV?nc  
y`Wty@  
结果输出为1，这种操作方式保证了当前的Matlab实体可以用于通信。 ?ZV/U!y

在winwrp界面，为增加和使用Matlab类型的目录库，我们需要如下步骤： MK%9:wZ  
1. 在FRED脚本编辑界面找到参考. RuLi,'u  
2. 找到Matlab Automation Server Type Library R/~p>apg8  
3. 将名字改为MLAPP e>} s;H,

在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix，PutWorkspaceData适用于存储一般的数据在工作区，并赋予其为变量，PutFullMatrix试用于复数数据。 Q- cFtu-w

4. 在探测面计算照度 H*d9l2,KZS  
5. 使用PutWorkspaceData发送照度数据到Matlab jZu[n)u'C
