    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。 ^M(`/1:  
    ()nKug`.@  
    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: 0qL V(L  
    enableservice('AutomationServer', true) 2 ]DCF  
    enableservice('AutomationServer') &ap`}^8pM  
    3:~l2KIP4  
    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 IglJEH[+  
    )`s;~_ZZ  
    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: gN, k/U8  
    1. 在FRED脚本编辑界面找到参考. _/jUs_W  
    2. 找到Matlab Automation Server Type Library =|gJb|?w  
    3. 将名字改为MLAPP Q@e*$<3  
    *qO]v9 j  
    %uz|NRB=  
    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。 ~.W=

    现在将脚本代码公布如下,此脚本执行如下几个步骤: @[5_C?2  
    1. 创建Matlab服务器。 M$&WM{Pr^  
    2. 移动探测面对于前一聚焦面的位置。 > h,y\uV1  
    3. 在探测面追迹光线 4/HY[FT  
    4. 在探测面计算照度 ~tg1N^]kV  
    5. 使用PutWorkspaceData发送照度数据到Matlab (0OSGG9  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ZTh?^}/  
    7. 用Matlab画出照度数据 rq<`(V'2  
    8. 在Matlab计算照度平均值 o <D3Y95b  
    9. 返回数据到FRED中 pcRF: ~TE
