    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。 SYsO>`/ )  
    ey9hrRMR  
    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: M"p%CbcI]  
    enableservice('AutomationServer', true) d(RMD  
    enableservice('AutomationServer') C:^ :^y  
    V*2 * 5hx  
    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 [$d]U.

    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: >m!Z$m([J  
    1. 在FRED脚本编辑界面找到参考. n=~!x  
    2. 找到Matlab Automation Server Type Library }m^^6h  
    3. 将名字改为MLAPP /!t:MK;

    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。 [) >Yp-n

    现在将脚本代码公布如下,此脚本执行如下几个步骤:  HRbv%  
    1. 创建Matlab服务器。 toD!RE  
    2. 移动探测面对于前一聚焦面的位置。 ~}ifwm'7 a  
    3. 在探测面追迹光线 `DSFaBj,  
    4. 在探测面计算照度 {%k[Z9*tO  
    5. 使用PutWorkspaceData发送照度数据到Matlab `~lG5|  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 tQT<1Q02i  
    7. 用Matlab画出照度数据 9$9a BW  
    8. 在Matlab计算照度平均值 1~E4]Ef:W  
    9. 返回数据到FRED中 $gYGnh_,Q
