    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>Pr`T?>  
    Q$ +6f,m#W  
    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: y0vJ@ %`  
    enableservice('AutomationServer', true) 'Qdea$o  
    enableservice('AutomationServer') :eIi^K z[  
    Hlhd6be  
    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 nQGl]2  
    ;w/@_!~  
    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: %k%%3L,  
    1. 在FRED脚本编辑界面找到参考. -pmb-#`M  
    2. 找到Matlab Automation Server Type Library 5{/uHscwLa  
    3. 将名字改为MLAPP )]}G8A

    a\m_Q{:  
    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。 Sq&r ;

    现在将脚本代码公布如下,此脚本执行如下几个步骤: IOA2/ WQu  
    1. 创建Matlab服务器。 Mj&G5R~_  
    2. 移动探测面对于前一聚焦面的位置。 uMx6:   
    3. 在探测面追迹光线 xX f,j#`"  
    4. 在探测面计算照度 azz=,^U#  
    5. 使用PutWorkspaceData发送照度数据到Matlab J>l?HK  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 3 daI_Nx>  
    7. 用Matlab画出照度数据 lArKfs/   
    8. 在Matlab计算照度平均值 dI%?uk  
    9. 返回数据到FRED中 1=Z!ZY}}e
