    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。 htQ;m)>J:  
    ,R8n,az  
    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: 0}6QO  
    enableservice('AutomationServer', true) E}Ljo  
    enableservice('AutomationServer') 7Onk!NH  
    6(,ItMbI  
    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 QaIi.* tic  
    CJ0$;et  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: bd.j,4^  
    1. 在FRED脚本编辑界面找到参考. hJ<:-u+yk}  
    2. 找到Matlab Automation Server Type Library 2$iw/ r  
    3. 将名字改为MLAPP M\9IlV?'

    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。 4 iik5

    现在将脚本代码公布如下,此脚本执行如下几个步骤: H&w(]PDh  
    1. 创建Matlab服务器。 LH bZjZ2  
    2. 移动探测面对于前一聚焦面的位置。 l.sm~/  
    3. 在探测面追迹光线 O.]_Ry\OXA  
    4. 在探测面计算照度 A&D2T  
    5. 使用PutWorkspaceData发送照度数据到Matlab vM5k4%D  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 G[ ,,L  
    7. 用Matlab画出照度数据 ="/R5fp  
    8. 在Matlab计算照度平均值 jM{qRfOrg  
    9. 返回数据到FRED中 \o0z@Ntq
