    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。 lS/l iI'Y  
    4nKlW_{,  
    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: oa6&?4K?F  
    enableservice('AutomationServer', true) (lt{$0   
    enableservice('AutomationServer') *Qy,?2  
    }NKnV3G/Z  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 ~2[mZias  
    Y?\PU{ O  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: -YY@[5x?u  
    1. 在FRED脚本编辑界面找到参考. gmN$}Gy}  
    2. 找到Matlab Automation Server Type Library nx@,oC4  
    3. 将名字改为MLAPP qv3% v3\4

    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。 eDY)i9"W

    现在将脚本代码公布如下,此脚本执行如下几个步骤: d0 ;<Cw~Tl  
    1. 创建Matlab服务器。 HM &"2c  
    2. 移动探测面对于前一聚焦面的位置。 Ww=b{lUD  
    3. 在探测面追迹光线 - *v)sP"@  
    4. 在探测面计算照度 0}N"L ml  
    5. 使用PutWorkspaceData发送照度数据到Matlab Q-Oj%w4e  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 YR u#JYti  
    7. 用Matlab画出照度数据 P.- `[  
    8. 在Matlab计算照度平均值 Q:8t1ZDo  
    9. 返回数据到FRED中 dgT(]H
