    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。 3EO#EYAHiM  
    E#m76]vkCU  
    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: []!tT-Gzy  
    enableservice('AutomationServer', true) - f+CyhR"*  
    enableservice('AutomationServer') 2zwuvgiZ  
    v#w4{.8)  
    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 ?! !;XW

    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: 0GF%~6  
    1. 在FRED脚本编辑界面找到参考. 3KbUHSx  
    2. 找到Matlab Automation Server Type Library +HYN$>  
    3. 将名字改为MLAPP UqY J#&MqY  
    x`wZtv\  
    ;H`=):U  
    在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 jD$;q7fB

    现在将脚本代码公布如下,此脚本执行如下几个步骤: h4B+0  
    1. 创建Matlab服务器。 T "ZQPLg  
    2. 移动探测面对于前一聚焦面的位置。 @w+WLeJ$40  
    3. 在探测面追迹光线 8s\8`2=  
    4. 在探测面计算照度 PL9zNCr-[  
    5. 使用PutWorkspaceData发送照度数据到Matlab i+kFL$N  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Tey,N^=ek  
    7. 用Matlab画出照度数据 Tq_1wX'\  
    8. 在Matlab计算照度平均值 t"jIfU>'a/  
    9. 返回数据到FRED中 2X qPZ]2g
