    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。 uj)yk*  
    +N7"EROc  
    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: Z4#v~!  
    enableservice('AutomationServer', true) =)(0.E  
    enableservice('AutomationServer') Z0 aUHWms  
    nX)f'[ 7  
    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 ;>8kPG

    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: BGN9, ii  
    1. 在FRED脚本编辑界面找到参考. ,%kmXh  
    2. 找到Matlab Automation Server Type Library 5\xr?`VZ  
    3. 将名字改为MLAPP EsTB(9c?

    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。 7LfcF

    现在将脚本代码公布如下,此脚本执行如下几个步骤: W tVf wC_  
    1. 创建Matlab服务器。 "T7>)fbu  
    2. 移动探测面对于前一聚焦面的位置。 Cs#w72N  
    3. 在探测面追迹光线 Q,~x#  
    4. 在探测面计算照度 [ZD[a6(94  
    5. 使用PutWorkspaceData发送照度数据到Matlab < <sE`>)  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Ik Qe~;Y  
    7. 用Matlab画出照度数据 }3J=DCtS  
    8. 在Matlab计算照度平均值 NJm-%K  
    9. 返回数据到FRED中 /kRAt^4!
