    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。 .YcI .  
    +Q6}kbDI  
    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: %>Y86>mVz  
    enableservice('AutomationServer', true) [<p7'n3x  
    enableservice('AutomationServer') Pf?y!d K<  
    Y]gb`z$?  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 sX$EdIq

    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_ hckq.  
    1. 在FRED脚本编辑界面找到参考. (R)(%I1Oz  
    2. 找到Matlab Automation Server Type Library U$5 lh  
    3. 将名字改为MLAPP `cBV+00YS  
    &?mJL0fy  
    m}dO\;  
    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。 ;.4A,7w#

    现在将脚本代码公布如下,此脚本执行如下几个步骤: i-`n5,  
    1. 创建Matlab服务器。 /?wH1 ,  
    2. 移动探测面对于前一聚焦面的位置。 UBy< vwnU  
    3. 在探测面追迹光线 1EvK\  
    4. 在探测面计算照度 ) ]x/3J@  
    5. 使用PutWorkspaceData发送照度数据到Matlab ni$S@0  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 x{';0MkUV  
    7. 用Matlab画出照度数据 EgT2a  
    8. 在Matlab计算照度平均值 ;>d uY\$<  
    9. 返回数据到FRED中 HX77XTy
