    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。 Dohl,d  
    EU&6 Tg  
    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`JlXuG?o  
    enableservice('AutomationServer', true) (mOqv9pn  
    enableservice('AutomationServer') rH [+/&w5  
    +aXMHT"U  
    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 i`ZHjW~`  
    DKaG?Y,*p  
    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: wh7i G8jCz  
    1. 在FRED脚本编辑界面找到参考. dvrvpDoE.  
    2. 找到Matlab Automation Server Type Library Lv`8jSt\  
    3. 将名字改为MLAPP 4jq`No_  
    5Tcl<Y6l  
    7>c 0V&  
    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。 Dn{19V. L

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Rd;~'gbG  
    1. 创建Matlab服务器。 ;c \zgs~"T  
    2. 移动探测面对于前一聚焦面的位置。 ~Q{[fy=  
    3. 在探测面追迹光线 Hz;jJ&S  
    4. 在探测面计算照度 4P-'(4I)  
    5. 使用PutWorkspaceData发送照度数据到Matlab af`f*{Co3  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 b'Piymx  
    7. 用Matlab画出照度数据 Sx4UaV~"  
    8. 在Matlab计算照度平均值 r~Is,.zZ}  
    9. 返回数据到FRED中 ] _]6&PZXk
