    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。 LTY.i3  
    qe$K6A%Yd  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: pj )I4C)  
    enableservice('AutomationServer', true) aFSZYyPxwv  
    enableservice('AutomationServer') n)=&=Uj`f  
    PLY7qM w  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 {'ZnxK'  
    K7l{&2>?  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: zyR pHM$E  
    1. 在FRED脚本编辑界面找到参考. foFn`?LF  
    2. 找到Matlab Automation Server Type Library S; c=6@"  
    3. 将名字改为MLAPP 67g/(4&  
    f*5"Jh@  
    ='JX_U`A^F  
    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。 )} #r"!

    现在将脚本代码公布如下,此脚本执行如下几个步骤: a@a1/ 3  
    1. 创建Matlab服务器。 us cR/d  
    2. 移动探测面对于前一聚焦面的位置。 TXaXJIp  
    3. 在探测面追迹光线 hnZHu\EJ  
    4. 在探测面计算照度 y,x~S\>+  
    5. 使用PutWorkspaceData发送照度数据到Matlab w#1dO~  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 g\.N>P@Bu  
    7. 用Matlab画出照度数据 f LW>-O73  
    8. 在Matlab计算照度平均值  @bx2=  
    9. 返回数据到FRED中 ~4^e a
