    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。 T%TO?[cN  
    BQgK<_  
    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: L1SZutWD?  
    enableservice('AutomationServer', true) V1,4M_Z  
        enableservice('AutomationServer') %NhZTmWm  
     </Dv?  
    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 )4GCL(&  
    w/ID y Q  
    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: *u>[  
    1. 在FRED脚本编辑界面找到参考. _^0UK|[  
    2. 找到Matlab Automation Server Type Library 0e'@Xo2e  
        3. 将名字改为MLAPP UQT=URS  
         I<&) P#"  
         YO.+ 06X  
    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。 kKVNE h Tp

    2. 移动探测面对于前一聚焦面的位置。 NF*Z<$'%  
    3. 在探测面追迹光线 Lnltt86  
    4. 在探测面计算照度 Jj+Hj[(@  
    5. 使用PutWorkspaceData发送照度数据到Matlab |s !7U  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 Pfg.'Bl  
    7. 用Matlab画出照度数据 1|7t q
