    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。 lUUeM\  
    qmv%N  
    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: {b= ]JPE  
    enableservice('AutomationServer', true) qL UbRp  
    enableservice('AutomationServer') 0bS\VUB(  
    UR:cBr  
    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 GC~Tfrf=r  
    jrZM  
    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: u ;f~  
    1. 在FRED脚本编辑界面找到参考. a 0Hzf  
    2. 找到Matlab Automation Server Type Library Q V4{=1A  
    3. 将名字改为MLAPP lLS`Ln)"

    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。 8;-a_VjA)

    现在将脚本代码公布如下,此脚本执行如下几个步骤: uiPfAPZ  
    1. 创建Matlab服务器。 qOqQt=ObU  
    2. 移动探测面对于前一聚焦面的位置。 ' DCrSa>  
    3. 在探测面追迹光线 3a"4Fn  
    4. 在探测面计算照度 7rbl+:y2  
    5. 使用PutWorkspaceData发送照度数据到Matlab M(0:>G  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 OB>Pk_eQK  
    7. 用Matlab画出照度数据 |!aMj8i2  
    8. 在Matlab计算照度平均值 NoV)}fX$X8  
    9. 返回数据到FRED中 +F]X
