F2mW<REg{ 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。
GP=&S|hi Uj>bWa` 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:
ykG^(.E enableservice('AutomationServer', true)
t
x#(K#/ enableservice('AutomationServer')
}e&Z"H |
-Deqlaf( 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。
O.OSLezTQ WB=|Ty~l 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:
&13#/ 1. 在FRED脚本编辑界面找到参考.
P}mn2Hs 2. 找到Matlab Automation Server Type Library
bJ9K!6s??` 3. 将名字改为MLAPP
2k"!o~s^ A \~tr _w49@9? 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。

[V.#w|n 1. 创建Matlab服务器。
y4N=v{EbL 2. 移动探测面对于前一聚焦面的位置。

光线 :/FT>UCL 4. 在探测面计算
照度 ;Fm7!@u^0 5. 使用PutWorkspaceData发送照度数据到Matlab
e'1}5Ky 6. 使用PutFullMatrix发送标量场数据到Matlab中
%P-z3 0FHp 7. 用Matlab画出照度数据
O{nM
