`Kg* 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。
{nj\dU BtU,1`El5 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:
u"C`S<c enableservice('AutomationServer', true)
JhB{aW> enableservice('AutomationServer')
R8":1 #&
Z!LzyCVl 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。
tkNuM0 !B-&I E? 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:
1<bSH n9 1. 在FRED脚本编辑界面找到参考.
J0o U5d=3 2. 找到Matlab Automation Server Type Library
} c&Zv#iO6 3. 将名字改为MLAPP
H26j]kY 0Apvuf1 >OiC].1
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。

n-H0cm 1. 创建Matlab服务器。
;9u6]%hQTX 2. 移动探测面对于前一聚焦面的位置。
n6|}^O7 3. 在探测面追迹
光线 jZm1.{[> 4. 在探测面计算
照度 L$7v;R3 5. 使用PutWorkspaceData发送照度数据到Matlab
9%\q* 6. 使用PutFullMatrix发送标量场数据到Matlab中
Z~$& h 7. 用Matlab画出照度数据
tk1qgjE(? 8. 在Matlab计算照度平均值
!u4oo- 9. 返回数据到FRED中
