=(Y 1y$ 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。
~( 54-9& ,iY/\
U'' 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:
c+|,qm enableservice('AutomationServer', true)
c%%r enableservice('AutomationServer')
|-GmW SK_
:SjTkfU 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。
UE33e(Q< L5=Tj4` 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:
`@eo <6 1. 在FRED脚本编辑界面找到参考.
Ch8w_Jf1yx 2. 找到Matlab Automation Server Type Library
WX$mAQDV 3. 将名字改为MLAPP
f|G,pDLx OoL#8R H7bdL 8/ 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。

G?e"A0, 1. 创建Matlab服务器。
8q*MhH>6I 2. 移动探测面对于前一聚焦面的位置。
d:jD 3. 在探测面追迹
光线 02OL-bv}HS 4. 在探测面计算
照度 -7\Rl3c 5. 使用PutWorkspaceData发送照度数据到Matlab
R?@F%J;tx 6. 使用PutFullMatrix发送标量场数据到Matlab中
ov>Rvy 7. 用Matlab画出照度数据
EooQLZ 8. 在Matlab计算照度平均值
rV.04m, 9. 返回数据到FRED中
