    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。 inBBU[Sl  
    $RfM}!7?  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: *am.NH\  
    enableservice('AutomationServer', true) ]2+7?QL,  
    enableservice('AutomationServer') cF7I  
    ]4ya$%A  
    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 ~:Dr   
    CD;C z*c  
    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: i"p)%q~ z  
    1. 在FRED脚本编辑界面找到参考. qe8dpI;  
    2. 找到Matlab Automation Server Type Library !U/iY%NE  
    3. 将名字改为MLAPP 6Xu8~%i  
    Y.$ '<1  
    g@BQ!}_#5  
    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。 h/j+ b.|

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Z_.Eale^  
    1. 创建Matlab服务器。 s_}T -%\  
    2. 移动探测面对于前一聚焦面的位置。 KWq7M8mq  
    3. 在探测面追迹光线 `L/kwVl  
    4. 在探测面计算照度 yCy4t6`e  
    5. 使用PutWorkspaceData发送照度数据到Matlab Mhc!v, D$  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 gNY}`'~hr  
    7. 用Matlab画出照度数据 wws)**]J8  
    8. 在Matlab计算照度平均值 M.iR5Uh  
    9. 返回数据到FRED中 RcIGIt
