    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。 Vi`P &uPF  
    ,T*\9' Q  
    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: 22'Ra[  
    enableservice('AutomationServer', true) }9kn;rb$g  
        enableservice('AutomationServer') bFhZSk )  
    sJ{r+wY  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 y+p"5s"  
    0t[ 1#!=k  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: ^5Zka!'X2Z  
    1. 在FRED脚本编辑界面找到参考. gO{$p q}  
    2. 找到Matlab Automation Server Type Library *zQhTYY  
        3. 将名字改为MLAPP OLo?=1&;;  
         ZUD{V  
         z\"9T?zoo  
    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。 rJh$>V+ '

    现在将脚本代码公布如下,此脚本执行如下几个步骤: AZf69z  
    1. 创建Matlab服务器。 W[sQ_Z1C  
    2. 移动探测面对于前一聚焦面的位置。 Jd~Mq9(  
    3. 在探测面追迹光线 P_5G'[  
    4. 在探测面计算照度 +@c$n`>)  
    5. 使用PutWorkspaceData发送照度数据到Matlab m&yHtnt  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 hXvC>ie(i  
    7. 用Matlab画出照度数据 L1WvX6  
    8. 在Matlab计算照度平均值 Xvk+1:D  
    9. 返回数据到FRED中 \r9E6LL X'
