/h(bMb Z 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。
L?Fb} H;1_" 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:
<n;9IU enableservice('AutomationServer', true)
F|wT']1Y enableservice('AutomationServer')
qh]D=i iAl.(j 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。
N6>ert1 [C0"vOTUb 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:
X21k7 Ls 1. 在FRED脚本编辑界面找到参考.
59@PY! c> 2. 找到Matlab Automation Server Type Library
D;Bij= 3. 将名字改为MLAPP
J4woZ{d r.JM!x8 w$evAPuz^ 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。

l^cz&k=+ Fd1t/B, KHTR oXt 现在将脚本代码公布如下,此脚本执行如下几个步骤:
K_Q-9j 1. 创建Matlab服务器。
y0R9[;b07 2. 移动探测面对于前一聚焦面的位置。
~_]i'ii8 3. 在探测面追迹
光线 B>kVJK`X 4. 在探测面计算
照度 `'vNHY 5. 使用PutWorkspaceData发送照度数据到Matlab
hN U.y 6. 使用PutFullMatrix发送标量场数据到Matlab中
.gJv})Vi 7. 用Matlab画出照度数据
<9/?+) 8. 在Matlab计算照度平均值
