    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。 M!PK3  
    s*>B"#En  
    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|VM{5  
    enableservice('AutomationServer', true) iSMVV<7  
    enableservice('AutomationServer') aU] nh. a  
     A1jA$  
    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 aSSw>*?Q  
    MG,?,1_ &  
    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: v)!^%D  
    1. 在FRED脚本编辑界面找到参考. &y2DI"Ff  
    2. 找到Matlab Automation Server Type Library Q>/[*(.Wd  
    3. 将名字改为MLAPP \#'m([<e  
    ?d)eri8,  
    E{B40E~4  
    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。 dM5N1$1,

    现在将脚本代码公布如下,此脚本执行如下几个步骤: SciEHI#  
    1. 创建Matlab服务器。 +]# p m9  
    2. 移动探测面对于前一聚焦面的位置。 *C^`+*}OE$  
    3. 在探测面追迹光线 kQtnT7  
    4. 在探测面计算照度 `lE8dwL  
    5. 使用PutWorkspaceData发送照度数据到Matlab Rd+ `b  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 &?SU3@3|  
    7. 用Matlab画出照度数据 !2=eau^p  
    8. 在Matlab计算照度平均值 y]%Io]!d  
    9. 返回数据到FRED中 % wh>_Ho
