    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。 D/'kYoAEO  
    IKMkpX!]  
    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: JQj?+PI  
    enableservice('AutomationServer', true) S4aN7.'Q  
    enableservice('AutomationServer') z8G1[ElY  
    z Xx HaM  
    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 ]wMd!.lm-  
    Fo=Icvo  
    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: f',n '  
    1. 在FRED脚本编辑界面找到参考. P%A;EF~ v  
    2. 找到Matlab Automation Server Type Library 7IB<0  
    3. 将名字改为MLAPP s {p-cV

    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。 26.),a

    现在将脚本代码公布如下,此脚本执行如下几个步骤: h.d-a/  
    1. 创建Matlab服务器。 1@rI4U@D  
    2. 移动探测面对于前一聚焦面的位置。 4{=zO(>  
    3. 在探测面追迹光线 [KR|m,QWp  
    4. 在探测面计算照度 1G$fU zS  
    5. 使用PutWorkspaceData发送照度数据到Matlab zP$0B!9  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 l2vIKc  
    7. 用Matlab画出照度数据 /'k4NXnW3  
    8. 在Matlab计算照度平均值 ebK/cPa8  
    9. 返回数据到FRED中 g X75zso
