[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。 =g{Hs1W  
IutU~%wv  
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： s_#6^_  
enableservice('AutomationServer', true) +nz0ZQ9 a  
enableservice('AutomationServer') Ex-?[Hq  

'n/L1Fn  
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。 m5 l,Lxj  
.1YiNmW=  
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： %4^NX@1jV  
1. 在FRED脚本编辑界面找到参考. 9CPr/q9'  
2. 找到Matlab Automation Server Type Library RfQ*`^D  
3. 将名字改为MLAPP ;!pSYcT,  
Btyp=wfN[  
(-%1z_@Y  
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。

现在将脚本代码公布如下，此脚本执行如下几个步骤： W0k7(v)  
1. 创建Matlab服务器。 ]S7>=S  
2. 移动探测面对于前一聚焦面的位置。 ^*'fDP*  
3. 在探测面追迹光线 cceh`s=cU  
4. 在探测面计算照度 Ctx{rf_~  
5. 使用PutWorkspaceData发送照度数据到Matlab 0S#T}ITm4Z  
6. 使用PutFullMatrix发送标量场数据到Matlab中 w`

7. 用Matlab画出照度数据 89P'WFOFK  
8. 在Matlab计算照度平均值 6
