    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。 z8xBq%97us  
    g1Osd7\o  
    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: >qd=lm <,  
    enableservice('AutomationServer', true) "w__AYHV  
        enableservice('AutomationServer') {P )O#  
    R'fEw3^  
    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 #G=AD/z

    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: %N0m$*  
    1. 在FRED脚本编辑界面找到参考. uJ0Wb$%  
    2. 找到Matlab Automation Server Type Library F&    
        3. 将名字改为MLAPP z|\n^ZK=  
         FW{K[km^P  
         zU_ dk'&,  
    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。 nwIj?(8x

    2. 移动探测面对于前一聚焦面的位置。 _/Ay$l;F

    4. 在探测面计算照度 oe!4ng[  
    5. 使用PutWorkspaceData发送照度数据到Matlab 7OS i2  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 Jm"W+! E  
    7. 用Matlab画出照度数据 d1'= \PYr
