    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。 ]f({`&K5  
    q*7VqB  
    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: k-{<=>uM  
    enableservice('AutomationServer', true) :FTMmW,>'  
    enableservice('AutomationServer') <U\B!fO'  
    Oz%>/zw[h  
    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 ^i} L-QR

    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: / :n#`o=;  
    1. 在FRED脚本编辑界面找到参考. Kiu_JzD  
    2. 找到Matlab Automation Server Type Library &?yZv {  
    3. 将名字改为MLAPP 7G>dTO  
    ]n~ilS.rkl  
    Tap.5jHL  
    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。 < RH UH)I

    现在将脚本代码公布如下,此脚本执行如下几个步骤: TmV,&['mg  
    1. 创建Matlab服务器。 [CXrSST")E  
    2. 移动探测面对于前一聚焦面的位置。 8Hn|cf0  
    3. 在探测面追迹光线 j4uvS!  
    4. 在探测面计算照度 ?}U(3  
    5. 使用PutWorkspaceData发送照度数据到Matlab %*0^0wz  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 h* u  
    7. 用Matlab画出照度数据 7OJ'){R$  
    8. 在Matlab计算照度平均值 70Wggty  
    9. 返回数据到FRED中 Pf\D-1gi
