    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。 Ob}XeN(L3  
    4O/IT1+A  
    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'F<1(  
    enableservice('AutomationServer', true) )[|_q,  
    enableservice('AutomationServer') B2a#:E,6  
    l(}MM|ka  
    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 : @eHV=|+>

    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: -GM"gkz  
    1. 在FRED脚本编辑界面找到参考. f=u +G  
    2. 找到Matlab Automation Server Type Library O .-n&U9  
    3. 将名字改为MLAPP hJD3G |E

    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。 =N8_S$nx(

    现在将脚本代码公布如下,此脚本执行如下几个步骤: wG9aX*(n  
    1. 创建Matlab服务器。 1 ltW9^cF}  
    2. 移动探测面对于前一聚焦面的位置。 [HUK 9hG  
    3. 在探测面追迹光线 f-ceDn  
    4. 在探测面计算照度 x<' $  
    5. 使用PutWorkspaceData发送照度数据到Matlab cza_LO(  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 72.Msnn  
    7. 用Matlab画出照度数据 {?2|rv)  
    8. 在Matlab计算照度平均值 !pkIaCxs  
    9. 返回数据到FRED中 C&R U
