    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。 /baSAoh/e  
    sK|+&BC  
    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: a~Y`N73/c  
    enableservice('AutomationServer', true) ^qNr<Ye  
    enableservice('AutomationServer') te#Wv9x  
    GNI:k{H@"?  
    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 V\r2=ok@y  
    !s[[X5  
    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: CdNb&Nyz  
    1. 在FRED脚本编辑界面找到参考. #HmZe98[%  
    2. 找到Matlab Automation Server Type Library %1kIaYZ  
    3. 将名字改为MLAPP 2$yNryd  
    l[b`4  
    Dq9*il;'  
    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。 C\gKJW^]y@

    现在将脚本代码公布如下,此脚本执行如下几个步骤: l !:kwF  
    1. 创建Matlab服务器。 C"g bol^  
    2. 移动探测面对于前一聚焦面的位置。 G9r~O#=gy  
    3. 在探测面追迹光线 18G=j@k7  
    4. 在探测面计算照度 !4(QeV-=  
    5. 使用PutWorkspaceData发送照度数据到Matlab ix_&<?8  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 _'Hw` 0}s  
    7. 用Matlab画出照度数据 wF$z ?L  
    8. 在Matlab计算照度平均值 7Nlk:f)*-  
    9. 返回数据到FRED中 jF0>w  m
