    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。 s?9$o Qq1  
    &*\-4)Tf  
    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: o9JZ -biH  
    enableservice('AutomationServer', true) (c\i.z  
    enableservice('AutomationServer') ExW3LM9(  
    -*nd5(lY&  
    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 FSNzBN  
    o-ee3j.  
    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: dBeZx1Dy  
    1. 在FRED脚本编辑界面找到参考. %"gV>E_u  
    2. 找到Matlab Automation Server Type Library &2Q0ii#Aa  
    3. 将名字改为MLAPP DxvD 1u   
    {0IC2jE  
    0;X0<IV  
    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。 u 6"v}gN

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ixjhZki<  
    1. 创建Matlab服务器。 }~bx==SF6!  
    2. 移动探测面对于前一聚焦面的位置。 >&-" X# :  
    3. 在探测面追迹光线 RLE6=#4  
    4. 在探测面计算照度 R]xXG0  
    5. 使用PutWorkspaceData发送照度数据到Matlab {sR|W:fS$  
    6. 使用PutFullMatrix发送标量场数据到Matlab中  x#hGJT  
    7. 用Matlab画出照度数据 An2Wj  
    8. 在Matlab计算照度平均值 0XLoGQ=  
    9. 返回数据到FRED中 ^;DbIo\6H
