    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。 lPp6 pVr  
    K P6PQgc  
    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: Xq%*# )M;  
    enableservice('AutomationServer', true) #NM JZ  
    enableservice('AutomationServer') ^Fvr f`A'  
    $kv[iI @  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 qZ?{-Vw  
    kxy]vH6m  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: jMqx   
    1. 在FRED脚本编辑界面找到参考. /=ACdJ  
    2. 找到Matlab Automation Server Type Library < 4$YO-:E  
    3. 将名字改为MLAPP fO+U HSC  
    & qL<C  
    19w_tSg  
    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。 xv&S[=Dt

    A?' H[2]w"  
    现在将脚本代码公布如下,此脚本执行如下几个步骤: @Q3, bj  
    1. 创建Matlab服务器。 8.-S$^hj~6  
    2. 移动探测面对于前一聚焦面的位置。 &58 {  
    3. 在探测面追迹光线 rFO_fIJno  
    4. 在探测面计算照度 ;x16shH  
    5. 使用PutWorkspaceData发送照度数据到Matlab QSv^l-<  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 H}a)^90_  
    7. 用Matlab画出照度数据 *@~`d*d  
    8. 在Matlab计算照度平均值 p4y6R4kyT  
    9. 返回数据到FRED中 >F~ITk5`Oo
