    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。 8j]QnH0&  
    Q.8^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: #\="^z6  
    enableservice('AutomationServer', true) iRW5*-66f  
    enableservice('AutomationServer') H- WNu+  
    G'HLnx}Yi  
    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 02^\np

    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: f~jd N~  
    1. 在FRED脚本编辑界面找到参考. v+C D{Tc  
    2. 找到Matlab Automation Server Type Library ,pZz`B#  
    3. 将名字改为MLAPP L^s?EqLXS

    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。 O9N%dir

    现在将脚本代码公布如下,此脚本执行如下几个步骤: "tK3h3/Xv  
    1. 创建Matlab服务器。 u7p:6W  
    2. 移动探测面对于前一聚焦面的位置。 bx".<q(  
    3. 在探测面追迹光线 Jju?v2y`  
    4. 在探测面计算照度 X5tV Xd  
    5. 使用PutWorkspaceData发送照度数据到Matlab s, #$o3  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Gv(n2r  
    7. 用Matlab画出照度数据 ~F~hgVS5  
    8. 在Matlab计算照度平均值 !VfVpi+-  
    9. 返回数据到FRED中 p7*7V.>X
