[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。 s9d_GhT%-  
8.~kK<)!  
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： a'z7(8$$  
enableservice('AutomationServer', true) D,ln
)["xm  
enableservice('AutomationServer')  Mc}^LDX  
Tb-F]lg$  
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。 snikn&

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： (4EI-e*6  
1. 在FRED脚本编辑界面找到参考. 9)=ctoZ'  
2. 找到Matlab Automation Server Type Library <Ok3FE.K  
3. 将名字改为MLAPP O| hpXkV

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。 zv"Z DRW

现在将脚本代码公布如下，此脚本执行如下几个步骤： E+JqWR5  
1. 创建Matlab服务器。 Oc; G(l(  
2. 移动探测面对于前一聚焦面的位置。 !?gKqx'T$  
3. 在探测面追迹光线 '`<w#z}AF  
4. 在探测面计算照度 GM<-&s!Uj  
5. 使用PutWorkspaceData发送照度数据到Matlab fd2T=fz-  
6. 使用PutFullMatrix发送标量场数据到Matlab中 6MkP |vr6  
7. 用Matlab画出照度数据 yvYad  
8. 在Matlab计算照度平均值 Tu7QCr5*  
9. 返回数据到FRED中 0K2`-mL
