    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。 m+gG &`&u  
    5tCq}]q#P  
    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: I\4`90uBN  
    enableservice('AutomationServer', true) _ L:w;Oy9T  
    enableservice('AutomationServer') ThQEQ6y  
    FLnAN;  
    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  v=Bh A9[  
    L!8?2 \5  
    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: I(kIHjV|  
    1. 在FRED脚本编辑界面找到参考. [Oy2&C  
    2. 找到Matlab Automation Server Type Library h}:5hi Jw  
    3. 将名字改为MLAPP ?yM/j7Xn  
    "s6_lhu=E7  
    u(G;57ms  
    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。 +5}T!r

    现在将脚本代码公布如下,此脚本执行如下几个步骤: mE@o27  
    1. 创建Matlab服务器。 >5},qs:lZ  
    2. 移动探测面对于前一聚焦面的位置。 U[ O!&:6  
    3. 在探测面追迹光线 /ykxVCvAt  
    4. 在探测面计算照度 9l^  
    5. 使用PutWorkspaceData发送照度数据到Matlab Q+js2?7^  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 "N:]d*A\  
    7. 用Matlab画出照度数据 j\L$dPZ  
    8. 在Matlab计算照度平均值 Glc4g  
    9. 返回数据到FRED中 pO+wJ|f
