Y^94iOk%T 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。
')~Y -A-hxK*^ 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:
AihL>a% enableservice('AutomationServer', true)
1{hoO<CJ enableservice('AutomationServer')
iXG>j.w{79
!UgUXN* 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。
quCWc2pXX }Pm(oR'KTJ 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:
.j:.WnW 1. 在FRED脚本编辑界面找到参考.
d=4f`q0k 2. 找到Matlab Automation Server Type Library
%!HnGwv- 3. 将名字改为MLAPP
\: _.N8" jL7MmR#y5" g+KzlS[6 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。

%.Tf u0M ?D~SHcBaN n?P 5pJ 现在将脚本代码公布如下,此脚本执行如下几个步骤:
X!+Mgh6 1. 创建Matlab服务器。
d*\C^:Z 2. 移动探测面对于前一聚焦面的位置。
Lx:N!RDw 3. 在探测面追迹
光线 B[0,\> 4. 在探测面计算
照度 Rvz.ym:F 5. 使用PutWorkspaceData发送照度数据到Matlab
J!
6z 6. 使用PutFullMatrix发送标量场数据到Matlab中
H;t8(-F@' 7. 用Matlab画出照度数据
WtdkA Sj 8. 在Matlab计算照度平均值
#HnyE+tD 9. 返回数据到FRED中
