    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。 PBgU/zVn  
    Ym 1; /'  
    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: URj2 evYW  
    enableservice('AutomationServer', true) uuYeXI;  
    enableservice('AutomationServer') -(9TM*)O  
    l]S%k&  
    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 Wx|De7*  
    b&*N  
    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: o`{^ptu1q  
    1. 在FRED脚本编辑界面找到参考. !H~PF*,hY  
    2. 找到Matlab Automation Server Type Library UHX,s  
    3. 将名字改为MLAPP ?P(U/DS8  
    ~$m:j];  
    z~#d@c\  
    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。 ;jFUtG

    现在将脚本代码公布如下,此脚本执行如下几个步骤: nT=XWM  
    1. 创建Matlab服务器。 S.!K  
    2. 移动探测面对于前一聚焦面的位置。 =J'&.@Dwz  
    3. 在探测面追迹光线 ,ygDNF  
    4. 在探测面计算照度 [I78<IJc  
    5. 使用PutWorkspaceData发送照度数据到Matlab @P<aTRy,f  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 .GIygU_  
    7. 用Matlab画出照度数据 -V=,x3Zew  
    8. 在Matlab计算照度平均值 o>A']+`E u  
    9. 返回数据到FRED中 vPD%5 AJN
