^l<!:SS 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。
mt~E&Z(A 8[;AFm ?,` 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:
re4A5Ev$ enableservice('AutomationServer', true)
OIDP#K enableservice('AutomationServer')
wjXv{EsMq
!j%uwje\ 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。
3YG%YhevO $]rC-K:Z 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:
zkquXzlgB 1. 在FRED脚本编辑界面找到参考.
Yv.7-DHNl 2. 找到Matlab Automation Server Type Library
g7{:F\S 3. 将名字改为MLAPP
tUt_Q;%yC ~C>clkZ ;iW>i8 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。

现在将脚本代码公布如下,此脚本执行如下几个步骤:
h_]*|[g 1. 创建Matlab服务器。
Y<V$3h 2. 移动探测面对于前一聚焦面的位置。
kj6H+@
{ 3. 在探测面追迹
光线 G[6i\Et 4. 在探测面计算
照度 Lrmhr3
w5 5. 使用PutWorkspaceData发送照度数据到Matlab
\AIFIy 6. 使用PutFullMatrix发送标量场数据到Matlab中
%CrTO( 7. 用Matlab画出照度数据
uAV7T /' 8. 在Matlab计算照度平均值
ZL:SJ,C 9. 返回数据到FRED中
