    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。 l?8M p$M  
    p(F" /  
    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: ;CHi\+` 5  
    enableservice('AutomationServer', true) @n&<B`/  
        enableservice('AutomationServer') tV;`fV   
    c{+AJ8  
    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 d[D&J  
     m#vL*]c}  
    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: 69K{+|  
    1. 在FRED脚本编辑界面找到参考. qZv =  
    2. 找到Matlab Automation Server Type Library +rXF{@ l  
        3. 将名字改为MLAPP DZS]AC*  
         ?, r~=  
         zSEs?  
    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。 8eBOr9l+j

    现在将脚本代码公布如下,此脚本执行如下几个步骤: (-77[+2  
    1. 创建Matlab服务器。 lv&mp0V+  
    2. 移动探测面对于前一聚焦面的位置。 "syh=BC v  
    3. 在探测面追迹光线 '*^yAlgtt  
    4. 在探测面计算照度 #oeG!<Mn  
    5. 使用PutWorkspaceData发送照度数据到Matlab *^\HU=&  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 2& PPz}Sw  
    7. 用Matlab画出照度数据 51C2u)HE  
    8. 在Matlab计算照度平均值 WEg6Kz  
    9. 返回数据到FRED中 3.d"rl
