    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。 o~<jayqU  
    J&Db-  
    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: O{7rIy  
    enableservice('AutomationServer', true) <5E)6c_W)  
    enableservice('AutomationServer') xM=ydRu  
    Sp6==(:.  
    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 .]H/u "d  
    4{Q$^wD+.  
    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: kbL7Xjk  
    1. 在FRED脚本编辑界面找到参考. b<!' WpY-  
    2. 找到Matlab Automation Server Type Library \2!.  
    3. 将名字改为MLAPP qnHjwMi  
    sSf;j,7V  
    T6b~uE  
    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。 lN&+<>a

    现在将脚本代码公布如下,此脚本执行如下几个步骤: mzCd@<T,  
    1. 创建Matlab服务器。 ,Ne9x\F  
    2. 移动探测面对于前一聚焦面的位置。 x ;~;Ah.p  
    3. 在探测面追迹光线 H,W8JNPs  
    4. 在探测面计算照度 nrA 4N1  
    5. 使用PutWorkspaceData发送照度数据到Matlab +PnuWK$  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 e_-7,5Co  
    7. 用Matlab画出照度数据 yZ!~m3Q  
    8. 在Matlab计算照度平均值 (-Q~@Q1  
    9. 返回数据到FRED中 2 FoLJ
