    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。 x^pHP|<3`  
    9w\C vO&R  
    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: j2n 4; m  
    enableservice('AutomationServer', true) oOQ0f |MGp  
    enableservice('AutomationServer') 9!D c=  
    . ve 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 8Y;>3z th7  
    o 7&q  
    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: oT}Sh4Wt.  
    1. 在FRED脚本编辑界面找到参考. h#|Ac>fz  
    2. 找到Matlab Automation Server Type Library )f%Q7  
    3. 将名字改为MLAPP 2&F  H8  
    `M_w^&6+n  
    2-"`%rE  
    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。 E `%*lGu_

    现在将脚本代码公布如下,此脚本执行如下几个步骤: :Ui'x8yt  
    1. 创建Matlab服务器。 Lez]{%+.`[  
    2. 移动探测面对于前一聚焦面的位置。 ` B+Pl6l)F  
    3. 在探测面追迹光线 -9"[/  
    4. 在探测面计算照度 0Jm)2@  
    5. 使用PutWorkspaceData发送照度数据到Matlab x^UAtKSy  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 `SYq/6$VEH  
    7. 用Matlab画出照度数据 0:>C v<N  
    8. 在Matlab计算照度平均值 CH=k=)() ]  
    9. 返回数据到FRED中 i$'#7U
