    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。 Mq> 4!  
    qk& F>6<9*  
    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: aT0~C.vT  
    enableservice('AutomationServer', true) N3G9o`k  
    enableservice('AutomationServer') !gX xM,R  
    <9@n/  
    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 SEgw!2H  
    m212 gc0u  
    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: Jm4uj &}3  
    1. 在FRED脚本编辑界面找到参考. hUMG}<  
    2. 找到Matlab Automation Server Type Library XFhH+4#]  
    3. 将名字改为MLAPP zhJeTctRz  
    T~UDD3  
    DGFSD Py[  
    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。 j7!u;K^c

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ucl001EK  
    1. 创建Matlab服务器。 J^+w]2`S  
    2. 移动探测面对于前一聚焦面的位置。 r5j$FwY  
    3. 在探测面追迹光线 \,;glY=M!  
    4. 在探测面计算照度 ".}R$ W  
    5. 使用PutWorkspaceData发送照度数据到Matlab <F3{-f'Rx  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Iy)1(upM  
    7. 用Matlab画出照度数据 24wDnDyh  
    8. 在Matlab计算照度平均值 k^7!iOK2  
    9. 返回数据到FRED中 *R6lK&
