    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。 M dKkj[#  
    Lnk(l2~U  
    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!rgR5Bd  
    enableservice('AutomationServer', true) Z)qts=  
    enableservice('AutomationServer') G _1`NyI  
    z\g6E/%%  
    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 f5tkv<) %  
    (?W[#.=7  
    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: D^-6=@<3KD  
    1. 在FRED脚本编辑界面找到参考. EEI !pi  
    2. 找到Matlab Automation Server Type Library rb_FBa%  
    3. 将名字改为MLAPP q{RH/. l  
    HzdyfZ!jR  
      mN^/  
    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。 (^lw<$N

    现在将脚本代码公布如下,此脚本执行如下几个步骤: b~Q8&z2  
    1. 创建Matlab服务器。 $>*TO1gb+  
    2. 移动探测面对于前一聚焦面的位置。 P \k5%  
    3. 在探测面追迹光线 5,~Ju>y*  
    4. 在探测面计算照度 Pbo759q 1  
    5. 使用PutWorkspaceData发送照度数据到Matlab m,|)$R  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 _(zPA4q8q  
    7. 用Matlab画出照度数据 WAzn`xGxR"  
    8. 在Matlab计算照度平均值 tqYwP Sr  
    9. 返回数据到FRED中 |,)=-21&;
