@ioJ]$o7 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。
xml7Uarc ,V m
< rK 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:
50wulGJud enableservice('AutomationServer', true)
}?i0
I enableservice('AutomationServer')
!hy-L_wL]
_Y4` xv0/ 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。
pa3{8x{9m <2x^slx)? 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:
n'LrQU 1. 在FRED脚本编辑界面找到参考.
q:0N<$63 2. 找到Matlab Automation Server Type Library
KYI/ 3. 将名字改为MLAPP
o[w:1q7 HM1Fz\Sf ~jk|4`I?T 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。

mdg8,n 4.aZ#c91_ v{N`.~,^ 现在将脚本代码公布如下,此脚本执行如下几个步骤:
]Q1yNtN 1. 创建Matlab服务器。
%)1?TU 2. 移动探测面对于前一聚焦面的位置。
M

光线 3(N$nsi 4. 在探测面计算
照度 U9 s& 5. 使用PutWorkspaceData发送照度数据到Matlab
&PHTpkaam 6. 使用PutFullMatrix发送标量场数据到Matlab中
{\1?ZrCI& 7. 用Matlab画出照度数据
bsli0FJSh' 8. 在Matlab计算照度平均值
$8h%a
