    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。 2gbMUdpp  
    #3o]Qo[Sc  
    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: ~ E|L4E  
    enableservice('AutomationServer', true) Z,bvD'u  
    enableservice('AutomationServer') %xWscA%^u  
    %*wOJx  
    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 zO07X*Bw  
    IRW%*W#  
    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: M`kR2NCi  
    1. 在FRED脚本编辑界面找到参考. MOEB{~v`;  
    2. 找到Matlab Automation Server Type Library U<lCK!85[  
    3. 将名字改为MLAPP :g[G&Ds8  
    34P5[j!h  
    9#AsSbBpf  
    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。 %<Q?|}

    :,^pLAt  
    现在将脚本代码公布如下,此脚本执行如下几个步骤: (iZE}qf7 g  
    1. 创建Matlab服务器。 ^v].mV/  
    2. 移动探测面对于前一聚焦面的位置。 4SqZ V  
    3. 在探测面追迹光线 6hs2B5)+  
    4. 在探测面计算照度 zu Jl #3YP  
    5. 使用PutWorkspaceData发送照度数据到Matlab wbaXRvg  
    6. 使用PutFullMatrix发送标量场数据到Matlab中  *R6n+d  
    7. 用Matlab画出照度数据 boR&'yX  
    8. 在Matlab计算照度平均值 @BZ6{@*  
    9. 返回数据到FRED中 Sh_=dzM
