    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。 qRu~$K  
    mupT<_Y  
    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: xPdG*OcX!  
    enableservice('AutomationServer', true) V~qNyOtA]  
    enableservice('AutomationServer') E[OJ+ ;c  
    uIY#e<)}G  
    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 O4 w(T  
    #j;^\rSv-  
    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: SA:Zc^aV  
    1. 在FRED脚本编辑界面找到参考. (xycJ`N  
    2. 找到Matlab Automation Server Type Library //B&k`u  
    3. 将名字改为MLAPP oE6tauQn

    }ZYd4h|g\z  
    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。 ^ "E^zHM(

    现在将脚本代码公布如下,此脚本执行如下几个步骤: "2!&5s,1p  
    1. 创建Matlab服务器。 Z<oaK  
    2. 移动探测面对于前一聚焦面的位置。 aNsBcov3O  
    3. 在探测面追迹光线 n>z9K')  
    4. 在探测面计算照度 Nd4f^Y   
    5. 使用PutWorkspaceData发送照度数据到Matlab KV91)U  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 'I|v[G$l  
    7. 用Matlab画出照度数据 _r#Z}HK  
    8. 在Matlab计算照度平均值 _!#@@O0p/h
