    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。 Cup@TET35  
    M~6@20$oW  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: RAs0]K  
    enableservice('AutomationServer', true) (y4#.vZh:  
    enableservice('AutomationServer') RBGlzk  
    {Z{o"56f  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 K_-d(  
    J?:[$C5  
    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: O,V9R rG  
    1. 在FRED脚本编辑界面找到参考. 1D([@)^  
    2. 找到Matlab Automation Server Type Library  ZC^C  
    3. 将名字改为MLAPP ^%oUmwP<$  
    HO|-@yOF^  
    Md; /nJO~{  
    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。 K=u0nrG*

    现在将脚本代码公布如下,此脚本执行如下几个步骤: q<=: >?  
    1. 创建Matlab服务器。 R -elIp  
    2. 移动探测面对于前一聚焦面的位置。 i&+w _hD  
    3. 在探测面追迹光线 GSVdb/+  
    4. 在探测面计算照度 rE!1wc>L  
    5. 使用PutWorkspaceData发送照度数据到Matlab *8g<R  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 2C+(":=}  
    7. 用Matlab画出照度数据 FY;+PY@I{  
    8. 在Matlab计算照度平均值 fJ80tt?r  
    9. 返回数据到FRED中 JSMPyj
