    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。 Ed>Dhy6\r  
    T`7HQf ;  
    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: w y\0o  
    enableservice('AutomationServer', true) rZi\  
    enableservice('AutomationServer') )*CDufRFz  
    Rt6(y #dF  
    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 oZ!1^o3V

    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: `Vf k.OP  
    1. 在FRED脚本编辑界面找到参考. 5Xr<~xr  
    2. 找到Matlab Automation Server Type Library 5L!cS+QNU  
    3. 将名字改为MLAPP d siQ~ [

    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。 gd,3}@@SH

    现在将脚本代码公布如下,此脚本执行如下几个步骤: %p(!7FDE2n  
    1. 创建Matlab服务器。 qrw"z iW  
    2. 移动探测面对于前一聚焦面的位置。 Z6S?xfhr'{  
    3. 在探测面追迹光线 f7y3BWOi]  
    4. 在探测面计算照度 [vV5@nP:  
    5. 使用PutWorkspaceData发送照度数据到Matlab .IkQo`_s:  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 &$V&gAN  
    7. 用Matlab画出照度数据 $[*QsU%%  
    8. 在Matlab计算照度平均值 u &qFE=5:
