    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\Y!vS  
    @WS77d~S  
    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: < A8>To<  
    enableservice('AutomationServer', true)  [. 9[?8  
    enableservice('AutomationServer') ERIMz ,  
    !pw )sO~  
    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 'xj5R=V  
    ;z.niX.fx  
    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: ~Ay)kv;  
    1. 在FRED脚本编辑界面找到参考. dB[4NT  
    2. 找到Matlab Automation Server Type Library ~[t#$2d}  
    3. 将名字改为MLAPP -wiQ d@X  
    n.2:fk  
    gh ?[x.U  
    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。 -'d:~:1f

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ;Go^)bN ;  
    1. 创建Matlab服务器。 iLuC_.'u=  
    2. 移动探测面对于前一聚焦面的位置。 HS{Vohy>  
    3. 在探测面追迹光线 ?#=xx.cF  
    4. 在探测面计算照度 i83~&Q=  
    5. 使用PutWorkspaceData发送照度数据到Matlab 8CZfz!2  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Fb]+h)on  
    7. 用Matlab画出照度数据 rN} 8~j  
    8. 在Matlab计算照度平均值 d7vPZ_j^z  
    9. 返回数据到FRED中 7[;!enO
