    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。 yh4jRe?f  
    XuA0.b%  
    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: ]~ >@%v&  
    enableservice('AutomationServer', true) @gY'YA8m  
    enableservice('AutomationServer') K"G(?<>~4c  
    3l.Nz@a*  
    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 !HbqbS22

    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: I"~xDa!  
    1. 在FRED脚本编辑界面找到参考. &boj$ k!g[  
    2. 找到Matlab Automation Server Type Library EF0Pt  
    3. 将名字改为MLAPP 7d%A1}Bq$  
    PlF89-  
    8x` Kl(  
    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。 ]kzv8#

    现在将脚本代码公布如下,此脚本执行如下几个步骤: sf<Q#ieTxY

    2. 移动探测面对于前一聚焦面的位置。 WFQ*s4 R(  
    3. 在探测面追迹光线 ?hP<@L6K  
    4. 在探测面计算照度 nmTm(?yE  
    5. 使用PutWorkspaceData发送照度数据到Matlab G%y>:$rw[O  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 .Gjr`6R  
    7. 用Matlab画出照度数据 ;*n_N!v  
    8. 在Matlab计算照度平均值 6yy|V~5  
    9. 返回数据到FRED中 N:"M&E UM
