    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。 JV;VR9-l  
    {v3@g[:|  
    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: =*?XZA)c  
    enableservice('AutomationServer', true) a5]]AkvA  
    enableservice('AutomationServer') v9D[| 4  
    ccW{88II7w  
    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 5 tVg++I  
    A~a7/N6s;  
    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: p|r>tBv?x  
    1. 在FRED脚本编辑界面找到参考. JS >"j d#  
    2. 找到Matlab Automation Server Type Library M7gqoJM'Q  
    3. 将名字改为MLAPP CS xB)-

    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。 ;[,#VtD

    1. 创建Matlab服务器。 )B^T7{  
    2. 移动探测面对于前一聚焦面的位置。 y=1(o3(  
    3. 在探测面追迹光线 (bogAi3<F  
    4. 在探测面计算照度 %(1y  
    5. 使用PutWorkspaceData发送照度数据到Matlab {RH)&k&%  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 PiX(Ase  
    7. 用Matlab画出照度数据 M[Jy?b)
