    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。 .L'>1H]B  
    +rS}f N$L.  
    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: ON~jt[  
    enableservice('AutomationServer', true) A=q)kcuy5  
    enableservice('AutomationServer') D_r&B@4w  
    Ij>IL!  
    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 [pf78

    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: -7)%J+5  
    1. 在FRED脚本编辑界面找到参考. 0?525^   
    2. 找到Matlab Automation Server Type Library Y9fktg.  
    3. 将名字改为MLAPP ]c,ttS _  
    L 1=HD  
    CqQ>"Y  
    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。 uNe5Mv|}

    现在将脚本代码公布如下,此脚本执行如下几个步骤: s-]k7a 2V  
    1. 创建Matlab服务器。 {Lu-!}\NP  
    2. 移动探测面对于前一聚焦面的位置。 5tI4m#y2  
    3. 在探测面追迹光线 qCg`"/0  
    4. 在探测面计算照度 ,w%cX{  
    5. 使用PutWorkspaceData发送照度数据到Matlab 4;@|tC|u  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 86!"b  
    7. 用Matlab画出照度数据 t3!?F(&  
    8. 在Matlab计算照度平均值 K:&FWl.  
    9. 返回数据到FRED中 -.= q6N4
