    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。 n b{8zo  
    @B[V'|  
    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: ;m\(fW*ii  
    enableservice('AutomationServer', true) t EN%mK  
        enableservice('AutomationServer') 2vur _`c V  
    0lEIj/u  
    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 h?SUDk:2^  
    d9^h YS{  
    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: j jwY{jV  
    1. 在FRED脚本编辑界面找到参考. H<q:+  
    2. 找到Matlab Automation Server Type Library rVO+ vhih  
        3. 将名字改为MLAPP I7}[%(~Sf/  
         r9QNE>UG  
         D4S>Pkv  
    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。 .$r(":A#)

    现在将脚本代码公布如下,此脚本执行如下几个步骤:  R` N-^x  
    1. 创建Matlab服务器。 6dNo!$C^  
    2. 移动探测面对于前一聚焦面的位置。 Z$@Juv&>5^  
    3. 在探测面追迹光线 ?>w%Lg{L}  
    4. 在探测面计算照度 Y/4B*>kl  
    5. 使用PutWorkspaceData发送照度数据到Matlab <?I~ +  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 mO\6B7V!  
    7. 用Matlab画出照度数据 Hu;#uAnxQ  
    8. 在Matlab计算照度平均值 @Pa ;h  
    9. 返回数据到FRED中 =A,i9Z&
