    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。 7h<Q{X<A  
    y VUA7IY  
    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: z* YkD"]B  
    enableservice('AutomationServer', true) p< '#f,o  
    enableservice('AutomationServer') "Q A#  
    ~LuZ pV  
    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 gf2l19aP

    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: ,4jkTQ*@2  
    1. 在FRED脚本编辑界面找到参考. CwTx7 ^qa  
    2. 找到Matlab Automation Server Type Library r{$ip"f  
    3. 将名字改为MLAPP mgL~ $

    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。 {tV)+T

    现在将脚本代码公布如下,此脚本执行如下几个步骤: U voX\  
    1. 创建Matlab服务器。 y!6B Gz  
    2. 移动探测面对于前一聚焦面的位置。 H`njKKdR  
    3. 在探测面追迹光线 7!#x-KR~5  
    4. 在探测面计算照度 {x W? v;  
    5. 使用PutWorkspaceData发送照度数据到Matlab 36*"oD=@  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 @R_a'v-  
    7. 用Matlab画出照度数据 Q'~kWmLf  
    8. 在Matlab计算照度平均值 Q` 4=  
    9. 返回数据到FRED中 Lz2wOB1Zc+
