    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。 c(8>oeKyD  
    M!gu`@@}F  
    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: S%?>Mh?g  
    enableservice('AutomationServer', true) 6yYd~|T.Fl  
    enableservice('AutomationServer') nHXPEbq-g  
    ^a3 (QKS  
    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 }NV<k  
    >N`, 3;Z  
    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: (C`nBiL<  
    1. 在FRED脚本编辑界面找到参考. Ik5-ooZ&{  
    2. 找到Matlab Automation Server Type Library N@'l: N'f4  
    3. 将名字改为MLAPP i[.7 8K-s

    X>yE<ni  
    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。 zh?B-"O=5

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Ym -U{a  
    1. 创建Matlab服务器。 u0[O /G  
    2. 移动探测面对于前一聚焦面的位置。 /K+;HAUTn  
    3. 在探测面追迹光线 Ft:_6T%  
    4. 在探测面计算照度 dKchQsgCg  
    5. 使用PutWorkspaceData发送照度数据到Matlab ~<Wa$~oY  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 @\-*aS_8>  
    7. 用Matlab画出照度数据 Rdd9JJsVd  
    8. 在Matlab计算照度平均值 T{#=A$vu  
    9. 返回数据到FRED中 `-W4/7
