    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。 Rt$Q *`u   
    N'L3Oa\%  
    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: )~q@2^  
    enableservice('AutomationServer', true) 3>[_2}l  
    enableservice('AutomationServer') l vuoVINEp  
    _)q,:g~fu  
    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 )V!dmVQq{g  
    c\.8hd=<  
    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: O -a`A.  
    1. 在FRED脚本编辑界面找到参考. 8^3Z]=(Q  
    2. 找到Matlab Automation Server Type Library t]Ey~-Rx  
    3. 将名字改为MLAPP 5feCA ,v7  
    .\0PyV(  
    b"+ J8W  
    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。 GS^U6Xef

    L#'B-G4&y  
    现在将脚本代码公布如下,此脚本执行如下几个步骤: @u./VK  
    1. 创建Matlab服务器。 `P&L. m]|  
    2. 移动探测面对于前一聚焦面的位置。 P)?)H]J"  
    3. 在探测面追迹光线 gA e*kf1  
    4. 在探测面计算照度 9aw- n*<  
    5. 使用PutWorkspaceData发送照度数据到Matlab +zpmy3Q  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 pn6 e{   
    7. 用Matlab画出照度数据 Vi~9[&.E\!  
    8. 在Matlab计算照度平均值 G]fl33_}l  
    9. 返回数据到FRED中 lY5a=mwHU
