[技术]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。 FVHL;J]nf1  
0;9LIL5  
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： e)M1$  
enableservice('AutomationServer', true) M:~#"lfK  
enableservice('AutomationServer') [,c>-jA5  
QB7<$Bp  
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。 >_o_&;=`v

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： Ok@5`?08  
1. 在FRED脚本编辑界面找到参考. AG?oA328  
2. 找到Matlab Automation Server Type Library VC@o]t5  
3. 将名字改为MLAPP @AwH?7(b

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。 A6d+RAx

现在将脚本代码公布如下，此脚本执行如下几个步骤： ^6=nL<L  
1. 创建Matlab服务器。 q#Bdq8  
2. 移动探测面对于前一聚焦面的位置。 xc!"?&\*  
3. 在探测面追迹光线 ;tHF$1!J  
4. 在探测面计算照度 *(rq AB0~  
5. 使用PutWorkspaceData发送照度数据到Matlab #pZ3xa3R  
6. 使用PutFullMatrix发送标量场数据到Matlab中 gP}M\3-O  
7. 用Matlab画出照度数据 '&`Zy pq  
8. 在Matlab计算照度平均值 }*%

9. 返回数据到FRED中 ^^v!..V]J
