    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。 y1AS^'  
    jBB<{VV|  
    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: aY?}4Bx  
    enableservice('AutomationServer', true) +X- k)9  
    enableservice('AutomationServer') LS_QoS  
    ']rh0?  
    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 !C+25vup  
    EfUo<E  
    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: vLC&C-f  
    1. 在FRED脚本编辑界面找到参考. h FjW.~B  
    2. 找到Matlab Automation Server Type Library r94BEC 2  
    3. 将名字改为MLAPP [AGm%o=)

    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。 Iq52rI}

    现在将脚本代码公布如下,此脚本执行如下几个步骤: un/R7 "  
    1. 创建Matlab服务器。 [v&_MQ  
    2. 移动探测面对于前一聚焦面的位置。 "8rP?B(  
    3. 在探测面追迹光线 ae<KUThm.  
    4. 在探测面计算照度 Ue\&  
    5. 使用PutWorkspaceData发送照度数据到Matlab 7oWv'  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 :I7MP   
    7. 用Matlab画出照度数据 61KJ( rSX3  
    8. 在Matlab计算照度平均值 ] x Kmz  
    9. 返回数据到FRED中 4EELaP|%
