    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。 Ol:&cX3G  
    * 7.!"rb8A  
    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: oC>e'_6_b  
    enableservice('AutomationServer', true) y%k\=:m  
    enableservice('AutomationServer') )I{41/_YA  
    l]inG^s  
    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 lDO9GNz$

    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: ( =0W[@k  
    1. 在FRED脚本编辑界面找到参考. R6] /g  
    2. 找到Matlab Automation Server Type Library =v=a:e  
    3. 将名字改为MLAPP ;oV dkp

    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。 8I$B^,N

    现在将脚本代码公布如下,此脚本执行如下几个步骤: [Rw0']i`4  
    1. 创建Matlab服务器。 CL|t!+wU/  
    2. 移动探测面对于前一聚焦面的位置。 dON 4r2-yC  
    3. 在探测面追迹光线 Jf@M>BT^A  
    4. 在探测面计算照度 KOGbC`TN<  
    5. 使用PutWorkspaceData发送照度数据到Matlab u_s  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 w-};\]I  
    7. 用Matlab画出照度数据  y$7Fq'  
    8. 在Matlab计算照度平均值 LGKkT?fcSC  
    9. 返回数据到FRED中 X|t?{.p
