    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。 *jM~VTXwt  
    %m$TV@  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: ]`)50\pdw  
    enableservice('AutomationServer', true) ^Lr)STh  
        enableservice('AutomationServer') (dn(:<_$  
     5 fY\0  
    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 _Bm/v^(  
    A@-nn]  
    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: #D~atgR  
    1. 在FRED脚本编辑界面找到参考. @ de_|*c  
    2. 找到Matlab Automation Server Type Library d%VG@./xq  
        3. 将名字改为MLAPP |3`Sd;^;  
         #ak2[UOT  
         :fz&)e9  
    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。 <cm,U)j2

    现在将脚本代码公布如下,此脚本执行如下几个步骤: IH8^ fyQ`  
    1. 创建Matlab服务器。 %> Z;/j|#r  
    2. 移动探测面对于前一聚焦面的位置。 |fnP@k  
    3. 在探测面追迹光线 Hv2t_QjKT  
    4. 在探测面计算照度 OEmz`JJ67  
    5. 使用PutWorkspaceData发送照度数据到Matlab "Opk:;.  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 gjB36R  
    7. 用Matlab画出照度数据 2Pn  
    8. 在Matlab计算照度平均值 k4r;t: O^  
    9. 返回数据到FRED中 5W_u|z+/g
