    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。 zx"s*:O  
    shy-Gu&  
    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: urs,34h  
    enableservice('AutomationServer', true) wY{-BuXv  
    enableservice('AutomationServer') +aCv&sg  
    TTX5EDCrC  
    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 hc(#{]].  
     j|DsG,  
    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: #?aPisV X>  
    1. 在FRED脚本编辑界面找到参考. *MFIV02[N  
    2. 找到Matlab Automation Server Type Library O-0x8O^B  
    3. 将名字改为MLAPP #_ ;lf1x!

    B?gOHG*vd>  
    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。 x*\Y)9Vgy

    现在将脚本代码公布如下,此脚本执行如下几个步骤: lV3x*4O=  
    1. 创建Matlab服务器。 \g&,@'uh  
    2. 移动探测面对于前一聚焦面的位置。 !OhC/f(GBZ  
    3. 在探测面追迹光线 d=$Mim  
    4. 在探测面计算照度 }^ ~F|  
    5. 使用PutWorkspaceData发送照度数据到Matlab $lfn(b,  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 $D~0~gn~  
    7. 用Matlab画出照度数据 >W=,j)MA  
    8. 在Matlab计算照度平均值 xf\C|@i  
    9. 返回数据到FRED中 }1L4 "}L.
