    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。 jJ^p ?  
    ]"'$i4I{R  
    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: DDdMWH^o7  
    enableservice('AutomationServer', true) A?l.(qG C_  
    enableservice('AutomationServer') p(EV-^  
    D ff0$06Nq  
    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 SKTf=rY  
    b21c} rI3  
    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: $JKR,   
    1. 在FRED脚本编辑界面找到参考. Uj!3H]d  
    2. 找到Matlab Automation Server Type Library oj.f uJD  
    3. 将名字改为MLAPP VgfA&?4[

    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。 0fgt2gA33

    现在将脚本代码公布如下,此脚本执行如下几个步骤: gXtyl]K:  
    1. 创建Matlab服务器。 X"V,3gDG  
    2. 移动探测面对于前一聚焦面的位置。 0!v+ +  
    3. 在探测面追迹光线 J!?hajw7N  
    4. 在探测面计算照度 9IFK4>&O6  
    5. 使用PutWorkspaceData发送照度数据到Matlab YGy.39@31  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 :S Tj <  
    7. 用Matlab画出照度数据 \B _g=K  
    8. 在Matlab计算照度平均值 ?yKW^,q+  
    9. 返回数据到FRED中 c"X`OB
