    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。 i;67< f}-  
    o6X<FE#8  
    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: NV^n}]ci  
    enableservice('AutomationServer', true) ?osYs<k \  
        enableservice('AutomationServer') 3UcOpq2i\  
    ks8xxY  
    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 ,`(Qs7)Xx  
    2yV {y#\   
    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: )7F$:*e  
    1. 在FRED脚本编辑界面找到参考. tTe:Oq  
    2. 找到Matlab Automation Server Type Library )1&,khd/u  
        3. 将名字改为MLAPP ^p~3H  
         6o GF6C  
         k= 9a/M 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。 Wp=:|J

    1. 创建Matlab服务器。 ~ [=2d a  
    2. 移动探测面对于前一聚焦面的位置。 iu'rc/=V  
    3. 在探测面追迹光线 G]I^zd&P  
    4. 在探测面计算照度 E"%G@,|3*  
    5. 使用PutWorkspaceData发送照度数据到Matlab I\VC2U  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 ,,(BW7(  
    7. 用Matlab画出照度数据 "\kr;X'  
    8. 在Matlab计算照度平均值 E2|c;{ c  
    9. 返回数据到FRED中 ;<v9i#K5
