    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。 OZ&o:/*HM  
    w2'5#`m  
    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: |l!aB(NW  
    enableservice('AutomationServer', true) ./~(7o$  
    enableservice('AutomationServer') Yr|4Fl~U  
    IVmo5,&5(  
    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 d"Y{UE  
    2t,zLwBdnJ  
    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: 8b=_Y;  
    1. 在FRED脚本编辑界面找到参考. P'rb%W  
    2. 找到Matlab Automation Server Type Library Q59W#e)  
    3. 将名字改为MLAPP T8NxJmYqB  
    sR8"3b<qA  
    A%-6`>  
    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。 p b,. r

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ,u!sjx  
    1. 创建Matlab服务器。 yDS4h(^  
    2. 移动探测面对于前一聚焦面的位置。 %XTI-B/K  
    3. 在探测面追迹光线 :@&/kyGH  
    4. 在探测面计算照度 Q@HV- (A  
    5. 使用PutWorkspaceData发送照度数据到Matlab OrG).^l  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 B erwI 7!=  
    7. 用Matlab画出照度数据 u=yOu^={  
    8. 在Matlab计算照度平均值 .e5Mnd%$M  
    9. 返回数据到FRED中 eQ}4;^;M-
