[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。 [C d"@!yA  
?z0f5<dL  
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： B;tU+36nM  
enableservice('AutomationServer', true) |,M&ks  
enableservice('AutomationServer') 3;=nQ{0b  
h+F@apUS  
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。 ;;'b;,/

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： CBdSgHA3>  
1. 在FRED脚本编辑界面找到参考. tdg.vYMDPC  
2. 找到Matlab Automation Server Type Library s>z$_  
3. 将名字改为MLAPP epa)ctS9

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。 d{+H|$L`

现在将脚本代码公布如下，此脚本执行如下几个步骤： pv039~Sud  
1. 创建Matlab服务器。 AfW63;kH  
2. 移动探测面对于前一聚焦面的位置。 Gxfw!aF~  
3. 在探测面追迹光线 )k0e}  
4. 在探测面计算照度 I!lzOg4~  
5. 使用PutWorkspaceData发送照度数据到Matlab ?^P#P0  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ~(Gv/x  
7. 用Matlab画出照度数据 cAC2Xq  
8. 在Matlab计算照度平均值 Pi::cf>3  
9. 返回数据到FRED中 NWPL18*C
