    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。 4ji'6JHPg  
    ,I+O;B:0  
    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: 2chT^3e  
    enableservice('AutomationServer', true) -em3 #V  
    enableservice('AutomationServer') {ehYE^%N  
    p)"EenUK  
    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 .L^;aL

    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: #)#'^MZX  
    1. 在FRED脚本编辑界面找到参考. IM[=]j.?  
    2. 找到Matlab Automation Server Type Library 6z/&j} (  
    3. 将名字改为MLAPP jv1p'qs4  
    )=aq j@v  
    @T.F/Pjhc  
    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。 {_z6

    现在将脚本代码公布如下,此脚本执行如下几个步骤: KVViTpZ  
    1. 创建Matlab服务器。 4"{g{8  
    2. 移动探测面对于前一聚焦面的位置。 2"P1I  
    3. 在探测面追迹光线 R iV]SgV 9  
    4. 在探测面计算照度 73tjDO7d  
    5. 使用PutWorkspaceData发送照度数据到Matlab @cm[]]f'l  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 !VrBoU4<d  
    7. 用Matlab画出照度数据 Qt^6w}&  
    8. 在Matlab计算照度平均值 9jl\H6JY|  
    9. 返回数据到FRED中 o$*DFvk
