    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。 7=WT69,&  
    Vz)`nmO}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: %$ Z7x\_  
    enableservice('AutomationServer', true) 2hkRd>)&5  
    enableservice('AutomationServer') % !>I*H  
    "a"]o  
    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 pDcjwlA%

    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: V=V:SlS9|  
    1. 在FRED脚本编辑界面找到参考. ac.Ms(D  
    2. 找到Matlab Automation Server Type Library ^Z# W_R\l  
    3. 将名字改为MLAPP U,q\em R

    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。 }36QsH8

    现在将脚本代码公布如下,此脚本执行如下几个步骤: $UCAhG$  
    1. 创建Matlab服务器。 I*kK 82  
    2. 移动探测面对于前一聚焦面的位置。 xA$nsZ]  
    3. 在探测面追迹光线 \z7SkZt,GT  
    4. 在探测面计算照度 h{p=WWK  
    5. 使用PutWorkspaceData发送照度数据到Matlab J@X'PG< 6B  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 lh D,\3/O  
    7. 用Matlab画出照度数据 oDYRQozo>  
    8. 在Matlab计算照度平均值 BWuqo  
    9. 返回数据到FRED中 ct,l^|0Hu8
