    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。 Wm}gnNwA  
    w3z'ZCcr;"  
    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: ,Js-'vX  
    enableservice('AutomationServer', true) M4D @G  
        enableservice('AutomationServer') '4_c;](W  
    P aeq  
    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 \KzH5?  
    cK >^8T^  
    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: &>B"/z  
    1. 在FRED脚本编辑界面找到参考. r6kJV4I=re  
    2. 找到Matlab Automation Server Type Library qZ4)) X  
        3. 将名字改为MLAPP Bgn%d4W;G  
         ;6~5FTmV  
         ,i1BoG  
    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。 PfyJJAQ[

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Xhq6l3M  
    1. 创建Matlab服务器。 _9JFlBx  
    2. 移动探测面对于前一聚焦面的位置。 eWN g?*/  
    3. 在探测面追迹光线 N .H<'Q8&  
    4. 在探测面计算照度 {z\K!=X/  
    5. 使用PutWorkspaceData发送照度数据到Matlab (^(l=EN-<  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 Wa7wV 9  
    7. 用Matlab画出照度数据 T2/:C7zL  
    8. 在Matlab计算照度平均值 #UhH  
    9. 返回数据到FRED中 r @m]#4
