    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。 ?p8k{N(1  
    &+nRIv S_`  
    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: 'UDBV  
    enableservice('AutomationServer', true) W$\X~Q'0  
    enableservice('AutomationServer') K^i"9D)A  
    M$CVQ>op:  
    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 "zV']A>4H  
    V; 9 }7mw  
    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: )}X5u%woV  
    1. 在FRED脚本编辑界面找到参考. 'm1.X-$V  
    2. 找到Matlab Automation Server Type Library |PM m?2^R  
    3. 将名字改为MLAPP rH}fLu8,;Q

    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。 v}il(w;O

    现在将脚本代码公布如下,此脚本执行如下几个步骤: lpEDPvD_Vm  
    1. 创建Matlab服务器。  Q&+c.S  
    2. 移动探测面对于前一聚焦面的位置。 Lk(S2$)*  
    3. 在探测面追迹光线 $U'3MEEw  
    4. 在探测面计算照度 r<FQX3  
    5. 使用PutWorkspaceData发送照度数据到Matlab F2oJ]th.3  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 52<~K  
    7. 用Matlab画出照度数据 >C2HC6O3  
    8. 在Matlab计算照度平均值 29O]S8  
    9. 返回数据到FRED中 H%.zXQ4}n
