    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。 `_.:O,^n^  
    +P+h$gQ  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: Gv]94$'J9  
    enableservice('AutomationServer', true) "*HEXru#B  
    enableservice('AutomationServer') $ r-rIW5\  
    6Ik v}q_j  
    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 @-0mE_$[

    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: w_"-rGV  
    1. 在FRED脚本编辑界面找到参考. v6wg,,T  
    2. 找到Matlab Automation Server Type Library %x;~ o:  
    3. 将名字改为MLAPP p<pGqW  
    *'?V>q,  
    Wm}T=L`  
    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。 J@i9)D_

    现在将脚本代码公布如下,此脚本执行如下几个步骤: b%x=7SMXO  
    1. 创建Matlab服务器。 H>D?  
    2. 移动探测面对于前一聚焦面的位置。 toU<InN  
    3. 在探测面追迹光线 )x?)v#k  
    4. 在探测面计算照度 }!r pH{y  
    5. 使用PutWorkspaceData发送照度数据到Matlab I d8MXdV  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 U)iBeYW:  
    7. 用Matlab画出照度数据 zRgGSxn  
    8. 在Matlab计算照度平均值 wmX(%5vY^  
    9. 返回数据到FRED中 !K2QD[x
