    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。 !8(: G6Ne  
    >hQeu1 ~W  
    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: |VQ17*4ff1  
    enableservice('AutomationServer', true) bj=kqO;*O  
    enableservice('AutomationServer') }4b 4<Sm_h  
    6w|s1!B l  
    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 =W$ f +  
    ;shhg z$  
    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: yY_Zq\   
    1. 在FRED脚本编辑界面找到参考. P>j^w#$n  
    2. 找到Matlab Automation Server Type Library 2+ m%f"  
    3. 将名字改为MLAPP 9`4M o+  
    ^{lcj  
    3copJS  
    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。 o'O;69D]tX

    现在将脚本代码公布如下,此脚本执行如下几个步骤: WdI9))J2S  
    1. 创建Matlab服务器。 ia6%>^  
    2. 移动探测面对于前一聚焦面的位置。 8w /$!9[  
    3. 在探测面追迹光线 7uQiP&v  
    4. 在探测面计算照度 B|XrjI?  
    5. 使用PutWorkspaceData发送照度数据到Matlab cBZ$$$v\#  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 j1D 1tn  
    7. 用Matlab画出照度数据 W<| M0S{  
    8. 在Matlab计算照度平均值 e!k1GTH^  
    9. 返回数据到FRED中 :+#$=4
