    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。 'Ul^V  
    iBt<EM]U/  
    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: u- }@^Y$M  
    enableservice('AutomationServer', true) R xA:>yOPn  
    enableservice('AutomationServer') JKF/z@Vbe\  
    N[zR%(YS  
    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 ;U&~tpd  
    |4j'KM;U  
    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: rNoCmNm  
    1. 在FRED脚本编辑界面找到参考. moD)^':.  
    2. 找到Matlab Automation Server Type Library $Xr4=9(|7  
    3. 将名字改为MLAPP MAc jWb~ f  
    }F';"ybrU)  
    W) ?s''WE;  
    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。 =lmelo#m&

    现在将脚本代码公布如下,此脚本执行如下几个步骤: pM-mZ/?  
    1. 创建Matlab服务器。 oi7Y?hTj  
    2. 移动探测面对于前一聚焦面的位置。 "uP~hFA7M  
    3. 在探测面追迹光线 r@c!M|m@  
    4. 在探测面计算照度 c{3P|O&.  
    5. 使用PutWorkspaceData发送照度数据到Matlab .1f!w!ltVR  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 J6mUU3F9f  
    7. 用Matlab画出照度数据 bH g 0,N  
    8. 在Matlab计算照度平均值 ()ww9L2  
    9. 返回数据到FRED中 pD]2.O
