    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。 SnF3I  
    c1IK9X*  
    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: mW_<c,3D.  
    enableservice('AutomationServer', true) gJNp]I2R  
        enableservice('AutomationServer') vG'JMzAm  
    GdqT4a\S  
    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 [TPr  
    Wmp,,H  
    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: silTL_$  
    1. 在FRED脚本编辑界面找到参考. P5+FZzQ  
    2. 找到Matlab Automation Server Type Library Q?GmSeUi  
        3. 将名字改为MLAPP 9w -t9X>X  
         cS98%@DR  
         6#+&_ #9  
    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。 Rx$5#K!%M

    现在将脚本代码公布如下,此脚本执行如下几个步骤: &Bbs\ ;  
    1. 创建Matlab服务器。 -WIT0F4o;  
    2. 移动探测面对于前一聚焦面的位置。 ^ ~HV`s  
    3. 在探测面追迹光线 DRLX0Ml]\  
    4. 在探测面计算照度 /@5X0m  
    5. 使用PutWorkspaceData发送照度数据到Matlab A f@IsCOJ  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 ) MFa~/x  
    7. 用Matlab画出照度数据 Gw6*0& 3')  
    8. 在Matlab计算照度平均值 }LNpr  
    9. 返回数据到FRED中 fbKL31PI
