    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。 M)CQ|P  
    Z%QU5.  
    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: Z=^~]Mfa  
    enableservice('AutomationServer', true) LNF|mS\+D  
    enableservice('AutomationServer') lD,;xuQ  
    7kmd.<  
    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 qjf9ZD&

    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: \6vr)1~N>  
    1. 在FRED脚本编辑界面找到参考. 8!qzG4F/  
    2. 找到Matlab Automation Server Type Library 'v_k #%  
    3. 将名字改为MLAPP ~Q+J1S]Fs  
    `$ZBIe/u  
    eV(   
    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。 i:x<Vi

    现在将脚本代码公布如下,此脚本执行如下几个步骤: D4PjE@D"H  
    1. 创建Matlab服务器。 ML:H\  
    2. 移动探测面对于前一聚焦面的位置。 #* Iyvx  
    3. 在探测面追迹光线 Y >U_l:_^  
    4. 在探测面计算照度 "/{H=X3was  
    5. 使用PutWorkspaceData发送照度数据到Matlab J@o$V- KK  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Q,n Xc  
    7. 用Matlab画出照度数据 P5`BrY,hZ  
    8. 在Matlab计算照度平均值 _dwJ;j`2  
    9. 返回数据到FRED中 3W55 m@w
