    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。 2]of SdM  
    ?V&Ld$db  
    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: ?/`C~e<J  
    enableservice('AutomationServer', true) p`E|SNt/W  
    enableservice('AutomationServer') J[j/aDdP  
    _1w.B8Lyz@  
    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 !#,-  
    B|]t\(~$ [  
    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: X7XCZSh#A  
    1. 在FRED脚本编辑界面找到参考. [M7iJcwt  
    2. 找到Matlab Automation Server Type Library pz*/4  
    3. 将名字改为MLAPP N3XVT{ yo  
    ct2_N  
    0UM@L }L  
    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。 ++J Bbuzj!

    现在将脚本代码公布如下,此脚本执行如下几个步骤: %KabyvOl)  
    1. 创建Matlab服务器。 /?.r!Cp  
    2. 移动探测面对于前一聚焦面的位置。 WryW3];0OR  
    3. 在探测面追迹光线 `'G),{ j  
    4. 在探测面计算照度 /ctaAQDUh\  
    5. 使用PutWorkspaceData发送照度数据到Matlab i GEQXIr3  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 CO:m]oj  
    7. 用Matlab画出照度数据 Y5h)l<P>B  
    8. 在Matlab计算照度平均值 b.mjQ  
    9. 返回数据到FRED中 Mv7w5vTl
