    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。 J+71FP`ZH  
    *,W!FxJ  
    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: BSfm?ku"!  
    enableservice('AutomationServer', true) '_.q_Tf-^  
    enableservice('AutomationServer') 2&.n  
    )+n,5W  
    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 zNV!@Yr  
    $!|8g`Tm  
    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: ceb s.sF:  
    1. 在FRED脚本编辑界面找到参考. b W=.K>|  
    2. 找到Matlab Automation Server Type Library X-)RU?  
    3. 将名字改为MLAPP wC(vr.,F  
    RIy5ww}3|  
    t['k%c  
    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。 Ew %{ i(d

    现在将脚本代码公布如下,此脚本执行如下几个步骤: c=A(o  
    1. 创建Matlab服务器。 ""1#bs{n  
    2. 移动探测面对于前一聚焦面的位置。 hWD !  
    3. 在探测面追迹光线 ORGv)>C|  
    4. 在探测面计算照度 q&XCX$N  
    5. 使用PutWorkspaceData发送照度数据到Matlab oA4D\rn8"  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 -}{%Q?rYj  
    7. 用Matlab画出照度数据 Zm%VG(l  
    8. 在Matlab计算照度平均值 qwq/Xcv  
    9. 返回数据到FRED中 lx\qp`w
