[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。 }5tn  
0RSa{iS*A  
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： C aJ
D*  
enableservice('AutomationServer', true) /l$noaskX  
enableservice('AutomationServer') xf]4!zE  
-X}R(.}x  
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。 wbS++cF<  
^&rbI,D  
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： &s<  
1. 在FRED脚本编辑界面找到参考. Csc2yI%3  
2. 找到Matlab Automation Server Type Library ,6buo~?W:  
3. 将名字改为MLAPP N8{>M,  
e#OU {2X  
+Ae.>%}  
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。 sk3;;<H

现在将脚本代码公布如下，此脚本执行如下几个步骤： kv4J@  
1. 创建Matlab服务器。 B&$89]gs|  
2. 移动探测面对于前一聚焦面的位置。 8Z!ea3kAT  
3. 在探测面追迹光线 _/=ZkI5  
4. 在探测面计算照度 2Ls<OO  
5. 使用PutWorkspaceData发送照度数据到Matlab PYf`a`dH  
6. 使用PutFullMatrix发送标量场数据到Matlab中 )yK!qu  
7. 用Matlab画出照度数据 -?'CUm*Od  
8. 在Matlab计算照度平均值 g:clSN,  
9. 返回数据到FRED中 yN o8R[M
