    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。 f[ER`!  
    \64(`6>  
    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: fnXl60C%  
    enableservice('AutomationServer', true) }B]FHpi  
        enableservice('AutomationServer') \SMH",u  
    %Z}dY~:  
    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 xt`znNN

    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: c=| a\\  
    1. 在FRED脚本编辑界面找到参考. TZHqn6  
    2. 找到Matlab Automation Server Type Library 0,/[r/=jT  
        3. 将名字改为MLAPP ' u0{h  
         / Sp+MB9  
         Dxu )by  
    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。 n09|Jzv9

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ]_-$  
    1. 创建Matlab服务器。 A"P1 B]  
    2. 移动探测面对于前一聚焦面的位置。 OPjscc5  
    3. 在探测面追迹光线 p]aIMF_  
    4. 在探测面计算照度 ''WX  
    5. 使用PutWorkspaceData发送照度数据到Matlab ?j OpW1  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 Y#N'bvE|%  
    7. 用Matlab画出照度数据 `[ne<F?e  
    8. 在Matlab计算照度平均值 v=W%|iZ  
    9. 返回数据到FRED中 .^v7LF]Q
