    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。 N* &T)a  
    *'A*!=5(  
    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: 1|xe'w{  
    enableservice('AutomationServer', true) `Ji WS  
    enableservice('AutomationServer') Udtz zka  
    'fb\t,  
    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 E' `;  
    U_PH#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: vWESu4W`L  
    1. 在FRED脚本编辑界面找到参考. 4XER 7c  
    2. 找到Matlab Automation Server Type Library $"|r7n5[  
    3. 将名字改为MLAPP KU(BY}/ ^  
    nM.g8d K

    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。  I2i'

    现在将脚本代码公布如下,此脚本执行如下几个步骤: @M<qz\ [  
    1. 创建Matlab服务器。 DMch88W  
    2. 移动探测面对于前一聚焦面的位置。 "~ $i#  
    3. 在探测面追迹光线 jR[c3EA ;  
    4. 在探测面计算照度 >]ux3F3\  
    5. 使用PutWorkspaceData发送照度数据到Matlab XK/l1E3N  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 [s]$&  
    7. 用Matlab画出照度数据 XPMUhozV  
    8. 在Matlab计算照度平均值 pA_u;*  
    9. 返回数据到FRED中 >5kz#|@P
