[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。 H]K(`)y}4  
+K,]#$k  
配置：在执行调用之前，我们需要在Matlab命令行窗口输入如下命令： NitWIj[
U;  
enableservice('AutomationServer', true) N '2
Nv  
enableservice('AutomationServer') V\r!H>   
*/fmy|#   
结果输出为1，这种操作方式保证了当前的Matlab实体可以用于通信。 &$ZJfHD@

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： gf7%vyMo$  
1. 在FRED脚本编辑界面找到参考. i7v> 9p7  
2. 找到Matlab Automation Server Type Library #?-2f{  
3. 将名字改为MLAPP >xb}AY;

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。 :t+XW`eQR:

现在将脚本代码公布如下，此脚本执行如下几个步骤： b"n0Yk1  
1. 创建Matlab服务器。 _0p8FhNt  
2. 移动探测面对于前一聚焦面的位置。 4/e|N#1`;[  
3. 在探测面追迹光线 Q{1Q w'+@  
4. 在探测面计算照度 Ey7SQb  
5. 使用PutWorkspaceData发送照度数据到Matlab &6V[@gmD  
6. 使用PutFullMatrix发送标量场数据到Matlab中 P0,@#M&  
7. 用Matlab画出照度数据 Y@N-q   
8. 在Matlab计算照度平均值 ( `T;nz  
9. 返回数据到FRED中 ?o307r
