    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。 !wh8'X*  
    o`z]|G1''  
    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: 5K8^WK  
    enableservice('AutomationServer', true) ~dTrf>R8M  
        enableservice('AutomationServer')  S9FE  
    u <v7;dF|s  
    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 M&9+6e'-F  
    =^,m` _1  
    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: Si;H0uPO  
    1. 在FRED脚本编辑界面找到参考. +Q"4Migbe@  
    2. 找到Matlab Automation Server Type Library P8/0H(,  
        3. 将名字改为MLAPP #BH*Z(  
         |#R7wnE[k~  
         Q K<"2p?  
    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。 V/9!K%y

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 5vnrA'BhBU  
    1. 创建Matlab服务器。 @?]RBX?a  
    2. 移动探测面对于前一聚焦面的位置。 gT6jYQ  
    3. 在探测面追迹光线 8$Y9ORs4  
    4. 在探测面计算照度 QD]6C2j*  
    5. 使用PutWorkspaceData发送照度数据到Matlab Vp@?^imL  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 88wa7i*  
    7. 用Matlab画出照度数据 _L=h0H l  
    8. 在Matlab计算照度平均值 YNsJZnGr8#  
    9. 返回数据到FRED中 r$s Qf&=
