    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。 ;65D  
    uO6{r v\  
    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: =0 qpVFvU  
    enableservice('AutomationServer', true) Y?K{(szo ?  
    enableservice('AutomationServer') 3j Z6kfj  
    ["3\eFg  
    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 2;2}wM[  
    Kibr ]w  
    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: d0'HDVd  
    1. 在FRED脚本编辑界面找到参考. #_i`#d)  
    2. 找到Matlab Automation Server Type Library !do?~$Og  
    3. 将名字改为MLAPP 9'[ N1Un.=  
    x,n,Qlb  
    o0bM=njok  
    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。 1} %B%*N

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 0Ua%DyJ  
    1. 创建Matlab服务器。 ,%9df+5k  
    2. 移动探测面对于前一聚焦面的位置。 K/=|8+IDL  
    3. 在探测面追迹光线 a<~77~"4wn  
    4. 在探测面计算照度 ocz G|_  
    5. 使用PutWorkspaceData发送照度数据到Matlab %]2, &  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 R?o$Y6}5  
    7. 用Matlab画出照度数据 oU*45B`"  
    8. 在Matlab计算照度平均值 r|u MovnV  
    9. 返回数据到FRED中 dG7OqA:9
