[分享]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。 Ac@zTK6>  
{k#RWDespy  
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： q&y9(ZvI  
enableservice('AutomationServer', true) g12mSbf=9  
enableservice('AutomationServer') %!_%%p,f  
mEM/}]2  
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。 j& x=?jX  
ji~P?5(:  
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： KW[Jft  
1. 在FRED脚本编辑界面找到参考. B&Igm<72x  
2. 找到Matlab Automation Server Type Library Gf|qc>j.b  
3. 将名字改为MLAPP nLfITr|5

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。 6}>:s

现在将脚本代码公布如下，此脚本执行如下几个步骤： /h!Y/\kI  
1. 创建Matlab服务器。 3?"JFfYU,'  
2. 移动探测面对于前一聚焦面的位置。 \~Yy

3. 在探测面追迹光线 @fVCGV?'  
4. 在探测面计算照度 LE"t'R  
5. 使用PutWorkspaceData发送照度数据到Matlab o5 fXe}pl@  
6. 使用PutFullMatrix发送标量场数据到Matlab中 %j[DG_  
7. 用Matlab画出照度数据 &>Ko}?w  
8. 在Matlab计算照度平均值 l*yh(3~}
