    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。 gY-}!9kW]  
    0R+<^6^l)  
    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: i2O$oHd  
    enableservice('AutomationServer', true) i"!j:YEo  
    enableservice('AutomationServer') 1RQM-0W,  
    C0e oV}  
    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 P]4u`&

    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: v>Kv!OY:c  
    1. 在FRED脚本编辑界面找到参考. $*0XWrE  
    2. 找到Matlab Automation Server Type Library ap|V}j C  
    3. 将名字改为MLAPP [DSzhi]

    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。 .YS48 c

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 9qJ:h-?M  
    1. 创建Matlab服务器。 gAGcbepX  
    2. 移动探测面对于前一聚焦面的位置。 pvqbk2BO  
    3. 在探测面追迹光线 eNt1P`2[  
    4. 在探测面计算照度 7tT L,Nxe  
    5. 使用PutWorkspaceData发送照度数据到Matlab j=b-Y  
    6. 使用PutFullMatrix发送标量场数据到Matlab中  D z>7.'3  
    7. 用Matlab画出照度数据 $xj>j  
    8. 在Matlab计算照度平均值 A}03s6^i;  
    9. 返回数据到FRED中 Q S.w#"X[
