Gs+\D0o! 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。
R;H?gE^m- 6exRS]BI 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:
CD^CUbGk enableservice('AutomationServer', true)
Vo #:CB=8 enableservice('AutomationServer')
7SBM^r}
:ar?0 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。
Uh>.v |P6 )8[ym/m 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:
-u6}T! 1. 在FRED脚本编辑界面找到参考.
i\(\MzW*' 2. 找到Matlab Automation Server Type Library
\M7I&~V 3. 将名字改为MLAPP
;4!=DFbU DC&A1I& h2"9"*S1 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。

VJ3hC[ 1. 创建Matlab服务器。
+W6Hva. 2. 移动探测面对于前一聚焦面的位置。
;P3>>DZ 3. 在探测面追迹
光线 #e*X0;m 4. 在探测面计算
照度 j8pFgnQ 5. 使用PutWorkspaceData发送照度数据到Matlab
fCB:733H 6. 使用PutFullMatrix发送标量场数据到Matlab中
8)sg_JC 7. 用Matlab画出照度数据
C*7!dW6 8. 在Matlab计算照度平均值
Wdo#?@m 9. 返回数据到FRED中
