    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。 Q9Tt3h2ga  
    \`ya08DP(  
    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: _wp>AJ r  
    enableservice('AutomationServer', true) t@#+vs@  
    enableservice('AutomationServer') }da}vR"iL  
    !?AgAsSmc  
    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 _*K=Z,a;\  
    fGZZ['E  
    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: Yz%AKp  
    1. 在FRED脚本编辑界面找到参考. ~J~@mE2ks  
    2. 找到Matlab Automation Server Type Library *Z9Rl>  
    3. 将名字改为MLAPP ILN Yh3

    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。 k?!CJ@5$

    现在将脚本代码公布如下,此脚本执行如下几个步骤: V4["+Y  
    1. 创建Matlab服务器。 b0(bL_,  
    2. 移动探测面对于前一聚焦面的位置。 i% FpPni  
    3. 在探测面追迹光线 ;hf{B7  
    4. 在探测面计算照度 ;7:_:o[.  
    5. 使用PutWorkspaceData发送照度数据到Matlab K~ch OX  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 (WCczXm)  
    7. 用Matlab画出照度数据 rtjUHhF  
    8. 在Matlab计算照度平均值 q0m> NA   
    9. 返回数据到FRED中 S9 p*rk ~
