    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。 -/^a2_d[  
    o2'^MxKb T  
    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: 2TQyQ%  
    enableservice('AutomationServer', true) =74yhPAW  
    enableservice('AutomationServer') 0c{-$K}  
    nDG41)|  
    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 ]2zzY::Sd=

    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: \eH`{Z'.x5  
    1. 在FRED脚本编辑界面找到参考. _;z IH5 H  
    2. 找到Matlab Automation Server Type Library mFk6a{+YX  
    3. 将名字改为MLAPP [hhPkJf|f

    :t)<$dtf[  
    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。 -F->l5

    1. 创建Matlab服务器。 NzBX2  
    2. 移动探测面对于前一聚焦面的位置。 $bo,m2)  
    3. 在探测面追迹光线 vx7wW<e%D  
    4. 在探测面计算照度 ]=ubl!0=:  
    5. 使用PutWorkspaceData发送照度数据到Matlab U"T>L  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ,$oz1,Q/  
    7. 用Matlab画出照度数据 sKCfI]
