    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。 {e+-vl  
    io#&o;M<  
    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: g.'yZvaP  
    enableservice('AutomationServer', true) n| b5? 3  
    enableservice('AutomationServer') P( XaTU&-  
    5B&;uY  
    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 0 ;b[QRmy

    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: E<C&Cjz:H  
    1. 在FRED脚本编辑界面找到参考. VH=S?_RY>  
    2. 找到Matlab Automation Server Type Library U$ F{nZ1  
    3. 将名字改为MLAPP z I+\Oll#Q

    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。 2gzou|Y

    现在将脚本代码公布如下,此脚本执行如下几个步骤: wE@'ap#  
    1. 创建Matlab服务器。 rAs,X  
    2. 移动探测面对于前一聚焦面的位置。 %H]lGN)  
    3. 在探测面追迹光线 Q %wY  
    4. 在探测面计算照度 =QK$0r]c'k  
    5. 使用PutWorkspaceData发送照度数据到Matlab m;D- u>o  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 {}QB|IH`  
    7. 用Matlab画出照度数据 ^bc;[x&N  
    8. 在Matlab计算照度平均值 d3W0-INL  
    9. 返回数据到FRED中 iJZ/jCI
