    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。 1R2IlUlzFr  
    IVR%H_uz  
    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:  1MN!  
    enableservice('AutomationServer', true) 3^sbbm.8  
    enableservice('AutomationServer') en<~_|J  
    8SGaS&  
    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 -YA,Stc-  
    n:5M E*  
    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: * ,hhX psa  
    1. 在FRED脚本编辑界面找到参考. l(t&<O(m9  
    2. 找到Matlab Automation Server Type Library \9?[|m z  
    3. 将名字改为MLAPP R;< q<i_l

    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。 X6HaC+P

    现在将脚本代码公布如下,此脚本执行如下几个步骤: q/i2o[f'n  
    1. 创建Matlab服务器。 s3>a  
    2. 移动探测面对于前一聚焦面的位置。 SVCh!/qe\  
    3. 在探测面追迹光线 qRt!kWW  
    4. 在探测面计算照度 -k'<6op  
    5. 使用PutWorkspaceData发送照度数据到Matlab $dL..QH^K  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 '}.Yf_  
    7. 用Matlab画出照度数据 KkJqqO"EL  
    8. 在Matlab计算照度平均值 ]VI^ hhf  
    9. 返回数据到FRED中 28MMH Q
