[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。 BE@(| U  
mTX:?

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： UwS7B~  
enableservice('AutomationServer', true) = >TU  
enableservice('AutomationServer') Bcv{Y\x;ko  
;AOLbmb)H4  
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。 jnJ*e-AW

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： y-.{){uaD  
1. 在FRED脚本编辑界面找到参考. (y!bvp[" m  
2. 找到Matlab Automation Server Type Library s;oe Qa}TB  
3. 将名字改为MLAPP w"[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。 y$-@|M$GG

现在将脚本代码公布如下，此脚本执行如下几个步骤： !^F_7u@Q  
1. 创建Matlab服务器。 qdpi-*2  
2. 移动探测面对于前一聚焦面的位置。 c$ib-
  
3. 在探测面追迹光线 &)Qq%\EP4  
4. 在探测面计算照度 =Y|( }92  
5. 使用PutWorkspaceData发送照度数据到Matlab 4bL *7
bA  
6. 使用PutFullMatrix发送标量场数据到Matlab中 [sH3REE1h  
7. 用Matlab画出照度数据 #|je m   
8. 在Matlab计算照度平均值 8=Oym~  
9. 返回数据到FRED中 LRu*%3xx
