~z*A%vp6ER 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。
SXm Hn.? gye'_AR?k 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:
|H@1g=q enableservice('AutomationServer', true)
%DF-;M"8 enableservice('AutomationServer')
a2`|6M;
N'e3< 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。
m}>#s3KPA 9..! g: 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:
Oxhc!9F 1. 在FRED脚本编辑界面找到参考.
94xRKQ} 2. 找到Matlab Automation Server Type Library
N\WEp?%~ 3. 将名字改为MLAPP
o+.LG($+U w%Tjn^ d *we*IhIP 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。

C%\. Wk&g!FR zz~AoX7V6 现在将脚本代码公布如下,此脚本执行如下几个步骤:
BjyGk+A 1. 创建Matlab服务器。
Z4'8x h)- 2. 移动探测面对于前一聚焦面的位置。
|oI] 3. 在探测面追迹
光线 %Ut7%obpi 4. 在探测面计算
照度 2n8spLZYGY 5. 使用PutWorkspaceData发送照度数据到Matlab
;p4|M 6. 使用PutFullMatrix发送标量场数据到Matlab中
;/]vmgl2 7. 用Matlab画出照度数据
g4
G?hv`R 8. 在Matlab计算照度平均值
\z>L,U 9. 返回数据到FRED中
