    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。 } r$&"wYM  
    XJy~uks,  
    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: 6M9t<DQV  
    enableservice('AutomationServer', true) )&]gX  
    enableservice('AutomationServer') Aifc0P-H  
    M*FUtu  
    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 sS;6QkI"y  
    ,#[0As29u  
    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: ~>&7~N8  
    1. 在FRED脚本编辑界面找到参考. O6Bs!0,  
    2. 找到Matlab Automation Server Type Library ~Q"3#4l  
    3. 将名字改为MLAPP E8gXa-hv

    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。 j78WPG

    现在将脚本代码公布如下,此脚本执行如下几个步骤: CsHHJgx  
    1. 创建Matlab服务器。 tJ[yx_mf  
    2. 移动探测面对于前一聚焦面的位置。 e5G)83[=  
    3. 在探测面追迹光线 HE58A.Q&  
    4. 在探测面计算照度 DhZuQpH  
    5. 使用PutWorkspaceData发送照度数据到Matlab 51j5AbFQ"  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 1=(jpy  
    7. 用Matlab画出照度数据 n&ZA rJ  
    8. 在Matlab计算照度平均值 ^Pl(V@  
    9. 返回数据到FRED中 %@ UH,Ew
