    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。 ][PzgzG  
    W\*-xf|"d  
    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: d4[(8} x$/  
    enableservice('AutomationServer', true) D6D1S/:ij'  
    enableservice('AutomationServer') dm rps+L  
    r WtZj}A  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 gA#RM5x@  
    YL^=t^ !4  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: @pV5}N[]  
    1. 在FRED脚本编辑界面找到参考. K2_Qu't0$  
    2. 找到Matlab Automation Server Type Library .o{0+fC#  
    3. 将名字改为MLAPP u}hF8eD  
    dHnR_.  
    }|)R   
    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。 AS!6XT

    现在将脚本代码公布如下,此脚本执行如下几个步骤:  84zTCX  
    1. 创建Matlab服务器。 k?nQ?B W  
    2. 移动探测面对于前一聚焦面的位置。 JF9yVE-  
    3. 在探测面追迹光线 ~0"p*?^  
    4. 在探测面计算照度 8Chj w wB  
    5. 使用PutWorkspaceData发送照度数据到Matlab >>dm }X  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 #PvB/3  
    7. 用Matlab画出照度数据 Huw\&E  
    8. 在Matlab计算照度平均值 AZ|yX  
    9. 返回数据到FRED中 n#Dv2 E=6
