j`"cU$NRM 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。
f>+:UGmP Oc^bbC 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:
bhT:MW! enableservice('AutomationServer', true)
D^2yP~( enableservice('AutomationServer')
MtK5>mhZI`
>c@1UEwkm 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。
v:Z.8m8D 9/50+2F 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:
a~;`&Uj 1. 在FRED脚本编辑界面找到参考.
a EqDxr6 2. 找到Matlab Automation Server Type Library
.sbV<ulbc 3. 将名字改为MLAPP
<k2]GI-}h e@L7p, AlT04H 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。

)V*V 1. 创建Matlab服务器。
2;=xHt 2. 移动探测面对于前一聚焦面的位置。
#3Jn_Y%P. 3. 在探测面追迹
光线 MQGR-WV=5 4. 在探测面计算
照度 sMAu* 5. 使用PutWorkspaceData发送照度数据到Matlab
n>I
N J 6. 使用PutFullMatrix发送标量场数据到Matlab中
9p<ZSh 7. 用Matlab画出照度数据
5J<ghv>\P 8. 在Matlab计算照度平均值
b$'}IWNV 9. 返回数据到FRED中
