    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。 :dQ B R  
    >)M`IU[d^.  
    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: ^>hWy D  
    enableservice('AutomationServer', true) %*0^0wz  
    enableservice('AutomationServer') EKsT~SS  
    m~-K[+ya`D  
    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 W)f/0QX}W  
    \S! e![L/  
    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: ]X ?7ZI^  
    1. 在FRED脚本编辑界面找到参考. jGpN,/VQa  
    2. 找到Matlab Automation Server Type Library s pp f  
    3. 将名字改为MLAPP zM(vr"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。 yU-e3O7L

    现在将脚本代码公布如下,此脚本执行如下几个步骤: K)DDk9*  
    1. 创建Matlab服务器。 P>NF.B Cq  
    2. 移动探测面对于前一聚焦面的位置。 a@UZb  
    3. 在探测面追迹光线 w.YiO5|y  
    4. 在探测面计算照度 dE4L=sTEsy  
    5. 使用PutWorkspaceData发送照度数据到Matlab F|e1"PkeoA  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 iA'lon  
    7. 用Matlab画出照度数据 rzm:Yx  
    8. 在Matlab计算照度平均值 YW( Qmo7  
    9. 返回数据到FRED中 V`XNDNJ:
