g 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。
d%I7OBBx@ U?dad}7 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:
a =W%x{ enableservice('AutomationServer', true)
[Q:mq=<Z% enableservice('AutomationServer')
yMdu
Zmkc
&w9*pJR % 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。
%KVmpWku b~UWFX#U 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:
^/2HH 1. 在FRED脚本编辑界面找到参考.
T
9`AL 2. 找到Matlab Automation Server Type Library
z4
=OR@ h 3. 将名字改为MLAPP
zf8SpQ2~ [4xZy5V ts<\n-f 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_( 现在将脚本代码公布如下,此脚本执行如下几个步骤:
oAifM1*0 1. 创建Matlab服务器。
'C}ku>B_r 2. 移动探测面对于前一聚焦面的位置。
+@uA 3. 在探测面追迹
光线 0,-]O= 4. 在探测面计算
照度 I~6(>Z{ 5. 使用PutWorkspaceData发送照度数据到Matlab
;HAvor=? 6. 使用PutFullMatrix发送标量场数据到Matlab中
i`52tH y_ 7. 用Matlab画出照度数据
:Z/\U*6~ 8. 在Matlab计算照度平均值
<V)z{uK 9. 返回数据到FRED中
