;^k7zNf- 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。
J QKdW @)YY\l# 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:
/L=(^k=a.; enableservice('AutomationServer', true)
(il0M=M enableservice('AutomationServer')
WPuz]Ty
P @%.`8 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。
8|1^|B(l h+UnZfm 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:
R""%F#4XJ2 1. 在FRED脚本编辑界面找到参考.
=ZYThfAEw 2. 找到Matlab Automation Server Type Library
,lN5,zI=S 3. 将名字改为MLAPP
A]`:VC=IU DtCEm(b0 A/*%J74v 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。

X~T/qFS 1. 创建Matlab服务器。
<EX7WA 2. 移动探测面对于前一聚焦面的位置。
C*Vd -U 3. 在探测面追迹
光线 %FkLQ+v/< 4. 在探测面计算
照度 .=RlOK 5. 使用PutWorkspaceData发送照度数据到Matlab
F}?<v8#z0 6. 使用PutFullMatrix发送标量场数据到Matlab中
NC23Z0y 7. 用Matlab画出照度数据
+JdZPb 8. 在Matlab计算照度平均值
T3J'fjY 9. 返回数据到FRED中
