    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。 wQb")3dw  
    `y0ZFh1>X  
    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: /7|u2!#Ui  
    enableservice('AutomationServer', true) 8gJ"7,}-'  
        enableservice('AutomationServer') ~FH''}3:3  
    &GwBxJ  
    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 2|tZ xlt-  
    dGQxGt1  
    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: 1W8[ RET  
    1. 在FRED脚本编辑界面找到参考. e+bpbyV_#  
    2. 找到Matlab Automation Server Type Library s!Y>\3rMW  
        3. 将名字改为MLAPP 6VolTy@(x  
         ]jG%<j9A  
         )gvX eJ  
    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。 wke$

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ~t<BZu  
    1. 创建Matlab服务器。 Ee9u7TFT  
    2. 移动探测面对于前一聚焦面的位置。 NeCTEe|V  
    3. 在探测面追迹光线 "<3PyW?zt  
    4. 在探测面计算照度 J\_tigd   
    5. 使用PutWorkspaceData发送照度数据到Matlab \`{ YqOT  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 P_hwa1~d  
    7. 用Matlab画出照度数据 "6 dC  
    8. 在Matlab计算照度平均值 0Z2![n  
    9. 返回数据到FRED中 o&rejj#
