    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。 4^MSX+zt  
    .q0AoM  
    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: Rf8:+d[Jj|  
    enableservice('AutomationServer', true) $nc, ?)i!  
    enableservice('AutomationServer') hOSf'mi  
    bQ=s8'  
    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 _3KZME  
    =u[rOU{X"W  
    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: %30T{n:  
    1. 在FRED脚本编辑界面找到参考. 9g+UJ\u^  
    2. 找到Matlab Automation Server Type Library >~>{;Wq(p+  
    3. 将名字改为MLAPP 9M0d+:YJ  
    #_,uE9  
    /9TL&_A-T  
    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。 IE@ z@+\(

    现在将脚本代码公布如下,此脚本执行如下几个步骤: w1.MhA  
    1. 创建Matlab服务器。 WkcH5[  
    2. 移动探测面对于前一聚焦面的位置。 ?bn;{c;E  
    3. 在探测面追迹光线 t3Qm-J}wSB  
    4. 在探测面计算照度 s.bT[0Vl  
    5. 使用PutWorkspaceData发送照度数据到Matlab `L+ ~&M  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 vsw7|  
    7. 用Matlab画出照度数据 O '@m4@L   
    8. 在Matlab计算照度平均值 qU}lGf!dVn  
    9. 返回数据到FRED中 a5>)?m
