    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。 ,??xW{* |  
    >\%44ba6  
    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: QV7K~qi  
    enableservice('AutomationServer', true) wE;??'O'l  
    enableservice('AutomationServer') (\>_{"*=  
    "\]kK @,  
    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 1KAA(W;nq  
    E.t9F3  
    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: ngn%"xYX  
    1. 在FRED脚本编辑界面找到参考. v`bX#\It  
    2. 找到Matlab Automation Server Type Library pNCk~OM  
    3. 将名字改为MLAPP !G Z2|~f9

    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。 fw'$HV76

    现在将脚本代码公布如下,此脚本执行如下几个步骤: )d_)CuUBe  
    1. 创建Matlab服务器。 >{$ ;O  
    2. 移动探测面对于前一聚焦面的位置。 {>pB  
    3. 在探测面追迹光线 YNH>^cD1  
    4. 在探测面计算照度 45W:b/n\  
    5. 使用PutWorkspaceData发送照度数据到Matlab v93+<@Z  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 \bZbz/+D  
    7. 用Matlab画出照度数据 >dn[oS,  
    8. 在Matlab计算照度平均值 0&$e:O'v  
    9. 返回数据到FRED中 i=#r JK=
