    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。 TKu68/\)  
    &W<>^C2v  
    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: j*~dFGl)  
    enableservice('AutomationServer', true) 6aZt4Lw2\  
        enableservice('AutomationServer') n!eqzr{  
    xZ=FH>Y6'  
    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 (X_,*3Yxk  
    skD k/-*R  
    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: 6Vbv$ AU  
    1. 在FRED脚本编辑界面找到参考. cm 9oG  
    2. 找到Matlab Automation Server Type Library &Pg-|Ql  
        3. 将名字改为MLAPP iVi3 :7*  
         )cqDvH  
         f,HzrHax  
    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。 m9<%v0r

    现在将脚本代码公布如下,此脚本执行如下几个步骤: K l0tyeT  
    1. 创建Matlab服务器。 E?gu(\an@  
    2. 移动探测面对于前一聚焦面的位置。 l^UJes!  
    3. 在探测面追迹光线 1'v!9  
    4. 在探测面计算照度 Q^MXiE O+  
    5. 使用PutWorkspaceData发送照度数据到Matlab IgiF,{KE,  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 ')u5l  
    7. 用Matlab画出照度数据 ]O7.ss/2  
    8. 在Matlab计算照度平均值 AXh3LA  
    9. 返回数据到FRED中 (4 /]dTb
