    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。 ,KFF[z  
    }II)<g'  
    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: 8[L]w^  
    enableservice('AutomationServer', true) ,u^%[ejH  
    enableservice('AutomationServer') $VnPs!a  
    s}g3*_"  
    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  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: ^F g!.X_  
    1. 在FRED脚本编辑界面找到参考. qx";G  
    2. 找到Matlab Automation Server Type Library T07 AH  
    3. 将名字改为MLAPP >gf,8flgj  
    h )h%y)1  
    W-<`Vo'  
    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。 Rv Uw,=

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 6!Uk c'r  
    1. 创建Matlab服务器。 K:54`UJ  
    2. 移动探测面对于前一聚焦面的位置。 t`pbEjE0K  
    3. 在探测面追迹光线 L|Bjw3K&D  
    4. 在探测面计算照度 tOxTiaa=  
    5. 使用PutWorkspaceData发送照度数据到Matlab &}!AjA)  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 h.4FY<  
    7. 用Matlab画出照度数据 4a zqH;i  
    8. 在Matlab计算照度平均值 #+(@i|!ifo  
    9. 返回数据到FRED中 (CrP6]=
