myDcr|j-a 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。
rIJd(= n<Z1i) 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:
O8 5) ^ enableservice('AutomationServer', true)
'~[JV>5 enableservice('AutomationServer')
w7yz4_:x^
qp2&Z8S\D 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。
Pa
*/&WeB :PQvt/-'(D 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:
_rvO#h 1. 在FRED脚本编辑界面找到参考.
2Z*^)ZQB 2. 找到Matlab Automation Server Type Library
@tPptB 3. 将名字改为MLAPP
<6!/B[!O= ^"EK:|Y4%K #~6au6LMC 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。

wU/BRz8I 7^DN8g"&\ ]BY<D`$$P 现在将脚本代码公布如下,此脚本执行如下几个步骤:
sjwD x0(7= 1. 创建Matlab服务器。
GA2kg7 2. 移动探测面对于前一聚焦面的位置。
L'<.#(| 3. 在探测面追迹
光线 @JpkG%eK 4. 在探测面计算
照度 P6u%-# 5. 使用PutWorkspaceData发送照度数据到Matlab
zAO|{m<A2 6. 使用PutFullMatrix发送标量场数据到Matlab中
aYcc2N%C 7. 用Matlab画出照度数据
GJn ~x 8. 在Matlab计算照度平均值
p]J0A ^VV 9. 返回数据到FRED中
