[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。

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： M_OvIU(E  
enableservice('AutomationServer', true) 1 +0-VRl  
enableservice('AutomationServer') ep$C nBwE  
mm l`,t8  
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。 FQ3{~05T

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： yx@%x?B  
1. 在FRED脚本编辑界面找到参考. 2`[iTBZ=^  
2. 找到Matlab Automation Server Type Library MMQ^&!H  
3. 将名字改为MLAPP xA&RMu&

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。 zc`gm~@

现在将脚本代码公布如下，此脚本执行如下几个步骤： (/^s?`1{N?  
1. 创建Matlab服务器。 `hVi!Q]*P  
2. 移动探测面对于前一聚焦面的位置。 ]RvFn~E!s  
3. 在探测面追迹光线 mr
6~8I  
4. 在探测面计算照度 ~OE1Sd:2  
5. 使用PutWorkspaceData发送照度数据到Matlab S.I3m-  
6. 使用PutFullMatrix发送标量场数据到Matlab中 -PG81F&K  
7. 用Matlab画出照度数据 vOIzfwYG9  
8. 在Matlab计算照度平均值 |*T`3@R;3  
9. 返回数据到FRED中 _oILZ,
