    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。 +TZVx(Z&A  
    @3w6 !Sgh  
    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`bl^~xRo  
    enableservice('AutomationServer', true) ;tJ}*!z W  
    enableservice('AutomationServer') pqCp>BO?O  
    SeV`RUO  
    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 cMfJq}C<  
    } =p e;l  
    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: UVd ^tg  
    1. 在FRED脚本编辑界面找到参考. <e?1&56  
    2. 找到Matlab Automation Server Type Library *@VS^JB  
    3. 将名字改为MLAPP ynZp|'b?<

    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。 +=`*`eP:U

    现在将脚本代码公布如下,此脚本执行如下几个步骤: !X5LgMw^;  
    1. 创建Matlab服务器。 !C&  ^%a  
    2. 移动探测面对于前一聚焦面的位置。 Z,~PW#8<&  
    3. 在探测面追迹光线 [$DI!%e|  
    4. 在探测面计算照度 "C.cU  
    5. 使用PutWorkspaceData发送照度数据到Matlab xrZzfg  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 {UFs1  
    7. 用Matlab画出照度数据 y]okOEV0  
    8. 在Matlab计算照度平均值 h3[x ZJO  
    9. 返回数据到FRED中 ${5E
