[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。 Y=\:fa  
`Y_G*b.Rm  
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： pi;'!d[l%  
enableservice('AutomationServer', true) S:8 WBY]M  
enableservice('AutomationServer') fOJTy0jX8  
k<}
3_   
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。 nN5fP<H2x  
$L"h|>b\o  
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： kY^ k*-v  
1. 在FRED脚本编辑界面找到参考. CWa~~h<r-  
2. 找到Matlab Automation Server Type Library FW)VyVFmk  
3. 将名字改为MLAPP ODNZLCB~t

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。 V_/.]zQA

现在将脚本代码公布如下，此脚本执行如下几个步骤： l!mx,O`  
1. 创建Matlab服务器。 _"[Ls?tRX  
2. 移动探测面对于前一聚焦面的位置。 $Ts;o  
3. 在探测面追迹光线 yS1i$[JV  
4. 在探测面计算照度 W5,&*mo  
5. 使用PutWorkspaceData发送照度数据到Matlab 5 BLAa1  
6. 使用PutFullMatrix发送标量场数据到Matlab中 C`qE ,2.  
7. 用Matlab画出照度数据 u~7fK  
8. 在Matlab计算照度平均值 7KL@[  
9. 返回数据到FRED中 Q?>DbT6
