    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。 $ T2 n^yz  
    yv+DM`0  
    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: HUWCCVn&  
    enableservice('AutomationServer', true) ^v+7IFn  
    enableservice('AutomationServer') ~i5t1  
    O_^X:0}  
    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 ,\CG}-v@CN

    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: Kc#42 C;t/  
    1. 在FRED脚本编辑界面找到参考. y&(R1Y75  
    2. 找到Matlab Automation Server Type Library 6v(;dolBIw  
    3. 将名字改为MLAPP ) mG

    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。 )K>2

    现在将脚本代码公布如下,此脚本执行如下几个步骤: U66}nN9  
    1. 创建Matlab服务器。 Ynx.$$`$=  
    2. 移动探测面对于前一聚焦面的位置。 MU#$tXmnC  
    3. 在探测面追迹光线 _ ATIV  
    4. 在探测面计算照度 R)u ${  
    5. 使用PutWorkspaceData发送照度数据到Matlab Q%Y r m  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ;Y"*Z2U  
    7. 用Matlab画出照度数据 Ng;Fhv+  
    8. 在Matlab计算照度平均值 j|c6BdROl  
    9. 返回数据到FRED中 FZJyqqA$_
