[推荐]FRED案例-FRED如何调用Matlab [复制链接]

^7b[spqE  
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。 D,$!.5OA  
d}d1]@Y\  
配置：在执行调用之前，我们需要在Matlab命令行窗口输入如下命令： dP[vXhc  
enableservice('AutomationServer', true) 1#nR$  
    enableservice('AutomationServer') ]IF QD  
?HD eiJkX  
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。 W^(:\IvV  
A=N &(k  
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： 8]G  
1. 在FRED脚本编辑界面找到参考. yT3q~#:  
2. 找到Matlab Automation Server Type Library ;dC>$_P?  
    3. 将名字改为MLAPP cx+w_D9b!

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。 oc|%|pmRd<

现在将脚本代码公布如下，此脚本执行如下几个步骤： "c+j2f'f  
1. 创建Matlab服务器。 6 b/UFO  
2. 移动探测面对于前一聚焦面的位置。 j<*  
3. 在探测面追迹光线 hq[:U?!Tt  
4. 在探测面计算照度 ! .q,m>?+  
5. 使用PutWorkspaceData发送照度数据到Matlab \r.{Ru  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 NE~R&ym9  
7. 用Matlab画出照度数据 g$^:2MT"aQ  
8. 在Matlab计算照度平均值 $Gy&  
9. 返回数据到FRED中 ?'xwr)v
