    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。 iPao54Z  
    |"arVde  
    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: ] GJskBm  
    enableservice('AutomationServer', true) nZ]d[  
        enableservice('AutomationServer') D*b> l_  
    .[7m4iJf  
    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 `y4+OXZ^  
    {az8*MR=X  
    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: GCrMrZ6  
    1. 在FRED脚本编辑界面找到参考. {"s8X(#_sC  
    2. 找到Matlab Automation Server Type Library .d;/6HD[y  
        3. 将名字改为MLAPP `eA0Z:`g!

         bR.T94-8y  
    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。 vg<_U&N=-r

    现在将脚本代码公布如下,此脚本执行如下几个步骤: eb7`R81G  
    1. 创建Matlab服务器。 =^6]N~*,D  
    2. 移动探测面对于前一聚焦面的位置。 rz4S"4  
    3. 在探测面追迹光线 7l?-2I'c  
    4. 在探测面计算照度 %"o4IYV#  
    5. 使用PutWorkspaceData发送照度数据到Matlab fV3J:^)F  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 +K&ze:-Z  
    7. 用Matlab画出照度数据 #+XKfumLk  
    8. 在Matlab计算照度平均值 &#~yci2{  
    9. 返回数据到FRED中 _uDtRoI8
