    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。 Z [68ji]  
    [0)iY%^  
    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: w5qhKu!1  
    enableservice('AutomationServer', true) u@==Ut  
    enableservice('AutomationServer') ]Ms~;MXlx5  
    e^Jy-?E  
    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 /SN.M6~  
    r"5]U`+  
    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: ] +Gi~  
    1. 在FRED脚本编辑界面找到参考. G V0q?  
    2. 找到Matlab Automation Server Type Library J fsCkS  
    3. 将名字改为MLAPP Yng9_w9Y

    y6:=2(]w<p  
    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。 %9Ulgs8=

    现在将脚本代码公布如下,此脚本执行如下几个步骤: %o^'(L@z  
    1. 创建Matlab服务器。 /\#qz.c2K  
    2. 移动探测面对于前一聚焦面的位置。 E37`g}ZS  
    3. 在探测面追迹光线 @iWIgL  
    4. 在探测面计算照度 hQ<"  
    5. 使用PutWorkspaceData发送照度数据到Matlab I:mJWe  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 oX?2fu-  
    7. 用Matlab画出照度数据 mE^6Zu  
    8. 在Matlab计算照度平均值 "%>/rh2Iq  
    9. 返回数据到FRED中 $lV0TCgba8
