[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。 :%MWbnVSC,  
? d\8Q't*  
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： e|yuPd  
enableservice('AutomationServer', true) q:.BY}X9  
enableservice('AutomationServer') .p>8oOp  
&}1)]6q$  
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。 ]]3D` F}  
q8>Q,F`BA  
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： EPy/6-5b  
1. 在FRED脚本编辑界面找到参考. Y&:i^k  
2. 找到Matlab Automation Server Type Library 'VEpVo/  
3. 将名字改为MLAPP `Cxe`w4

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。 9To6Rc;

现在将脚本代码公布如下，此脚本执行如下几个步骤： ] ),'=@  
1. 创建Matlab服务器。 Q>$L;1E*,  
2. 移动探测面对于前一聚焦面的位置。 .SN

3. 在探测面追迹光线 aa/9o]  
4. 在探测面计算照度 9<S-b |!@  
5. 使用PutWorkspaceData发送照度数据到Matlab <bI,y_<K  
6. 使用PutFullMatrix发送标量场数据到Matlab中 }}_l@5  
7. 用Matlab画出照度数据 [dMxr9M  
8. 在Matlab计算照度平均值 rI/KrBM  
9. 返回数据到FRED中 ]U%Tm>s.
