    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。 (UD@q>c  
    2%Ri,4SRb  
    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: oUlY?x1  
    enableservice('AutomationServer', true) 9!\B6=r y4  
    enableservice('AutomationServer') r.&Vw|*>  
    BsDn5\ q  
    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 <8&au(I,vB  
    R$<&ie6UQ  
    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: 9d659i C  
    1. 在FRED脚本编辑界面找到参考. Xza(k  
    2. 找到Matlab Automation Server Type Library ifQ*,+@fxR  
    3. 将名字改为MLAPP kd(8I_i@  
    ORw,)l  
    DU'`ewLL7  
    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。 lIS-4QX1

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ^A/k)x6  
    1. 创建Matlab服务器。 {$ JYw{a  
    2. 移动探测面对于前一聚焦面的位置。 6,"Q=9k4[  
    3. 在探测面追迹光线 B%b4v  
    4. 在探测面计算照度 L|xbR#v  
    5. 使用PutWorkspaceData发送照度数据到Matlab g-bK|6?yz  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 I3I/bofz  
    7. 用Matlab画出照度数据 ;bib/  
    8. 在Matlab计算照度平均值 DV-d(@`K  
    9. 返回数据到FRED中 5c0 ZRV#
