    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。 8^FAeV#  
    8A3pYW-  
    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: 9gLUM$Kd  
    enableservice('AutomationServer', true) uK5&HdoM  
    enableservice('AutomationServer') z#!}4@_i3  
    =Hs[peO*  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 \ &S-lsLY  
    kA1C&  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: '"/Yk=EmlU  
    1. 在FRED脚本编辑界面找到参考. keYvscRBI  
    2. 找到Matlab Automation Server Type Library IV5B5Q'D  
    3. 将名字改为MLAPP 'l| e}eti>  
    :GaK.W q  
    T1&^IO-F7$  
    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。 E =7m@"0

    现在将脚本代码公布如下,此脚本执行如下几个步骤: }bg_?o;X}  
    1. 创建Matlab服务器。 Gc'CS_L  
    2. 移动探测面对于前一聚焦面的位置。 3i c6!T#t"  
    3. 在探测面追迹光线 pRAdo="  
    4. 在探测面计算照度 @@O=a  
    5. 使用PutWorkspaceData发送照度数据到Matlab m<DiYxK  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 W=9Zl(2C  
    7. 用Matlab画出照度数据 4R~f   
    8. 在Matlab计算照度平均值 %bp8VR sY  
    9. 返回数据到FRED中 lOc!KZHUp
