    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。 UL"3skV   
    RN| ..zml  
    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: '$^ F.2  
    enableservice('AutomationServer', true) (}8 ;3pp  
    enableservice('AutomationServer') 3]'z8i({7Y  
    Ol0|)0  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 Z9^$jw]  
    [SvwJIJJ  
    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: EKD>c$T^  
    1. 在FRED脚本编辑界面找到参考. YTit=4|  
    2. 找到Matlab Automation Server Type Library O{R5<"g  
    3. 将名字改为MLAPP FI5C&d5d

    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。 C^tC} n1D(

    现在将脚本代码公布如下,此脚本执行如下几个步骤: *p!dd?8  
    1. 创建Matlab服务器。 \ChcJth@o<  
    2. 移动探测面对于前一聚焦面的位置。 TZ2f-KI  
    3. 在探测面追迹光线 N9<eU!4>  
    4. 在探测面计算照度 uoHhp4>^  
    5. 使用PutWorkspaceData发送照度数据到Matlab q Q8l8  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 bb/MnhB  
    7. 用Matlab画出照度数据 r&DK> H  
    8. 在Matlab计算照度平均值 +rY0/T_0,  
    9. 返回数据到FRED中 {`Z)'G\`
