6^W6As0 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。
ZS&n,<a5L} \hjGw,d 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:
.Z,3:3,] enableservice('AutomationServer', true)
|
HkLl^ enableservice('AutomationServer')
<b-BJ2],k
\5+?wpH 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。
_xg4;W6M= i\P?Y(-{ 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:
Fq{Z-yVp 1. 在FRED脚本编辑界面找到参考.
[x{S ,?6 2. 找到Matlab Automation Server Type Library
#q;hX;Va 3. 将名字改为MLAPP
ep"YGx[V w#?@ulr]d .U8Se+; 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。

b.qp&2 A :<-,[(@bR &cjE+ 现在将脚本代码公布如下,此脚本执行如下几个步骤:
~~U2Sr 1. 创建Matlab服务器。
I91pX<NBf 2. 移动探测面对于前一聚焦面的位置。
&*G+-cF 3. 在探测面追迹
光线 dx=\Pq 4. 在探测面计算
照度 QN %w\JXS 5. 使用PutWorkspaceData发送照度数据到Matlab
*wNX<R. 6. 使用PutFullMatrix发送标量场数据到Matlab中
vYh_<Rp5 7. 用Matlab画出照度数据
O1/U3/2/d 8. 在Matlab计算照度平均值
^y@RfM=A 9. 返回数据到FRED中
