    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。 jC-`u-_'j  
    a94 nB  
    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: F"tM?V.|  
    enableservice('AutomationServer', true) p-z!i+  
    enableservice('AutomationServer') e)L!4Y44K  
    t?;=\%^<  
    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 J|z' <W  
    6Tq2WZ}<'  
    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: 5mZ9rLn  
    1. 在FRED脚本编辑界面找到参考. ILHn~d IC  
    2. 找到Matlab Automation Server Type Library l`:-B 'WM  
    3. 将名字改为MLAPP G+3uY25y  
    E*v+@rv  
    #S|On[Q!  
    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。 f\:I1y

    y}W*P#BDO  
    现在将脚本代码公布如下,此脚本执行如下几个步骤: a^&RV5o  
    1. 创建Matlab服务器。 4LJOT_  
    2. 移动探测面对于前一聚焦面的位置。 `y1,VY  
    3. 在探测面追迹光线 (d[JMO^@8  
    4. 在探测面计算照度 6fT^t!<i  
    5. 使用PutWorkspaceData发送照度数据到Matlab 5YiBPB")  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ,`$2  
    7. 用Matlab画出照度数据 2%pe.s tQ  
    8. 在Matlab计算照度平均值 S2=x,c$  
    9. 返回数据到FRED中 $K 1)2WG
