    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。 ^pp\bVh2Q]  
    94'&b=5+  
    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: ~[t[y~Hup  
    enableservice('AutomationServer', true) n1Yp1"2b[  
    enableservice('AutomationServer') wON!MhA;  
    ` 'DmDg  
    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 KjD/o?JUr  
    T$8)u'-pa  
    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: w'>pY  
    1. 在FRED脚本编辑界面找到参考. =Qy<GeY  
    2. 找到Matlab Automation Server Type Library j`{?OYD  
    3. 将名字改为MLAPP =/@D8{pU  
    s:n6rG  
    sA+ }TNhq  
    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。 R)c?`:iUB

    现在将脚本代码公布如下,此脚本执行如下几个步骤: y6g&Y.:o  
    1. 创建Matlab服务器。 g_;\iqxL  
    2. 移动探测面对于前一聚焦面的位置。 fBU`k_  
    3. 在探测面追迹光线 'NWfBJm  
    4. 在探测面计算照度 /p/]t,-j2  
    5. 使用PutWorkspaceData发送照度数据到Matlab W_JlOc!y  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ./\@Km?  
    7. 用Matlab画出照度数据 s n8Qk=K  
    8. 在Matlab计算照度平均值 akmkyrz'&  
    9. 返回数据到FRED中 K%t*8 4j
