    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。 )~/U+,  
    T)uw2  
    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: [a3 0iE  
    enableservice('AutomationServer', true) I?>#neHc6  
        enableservice('AutomationServer') coWBKWF  
    -db+Y:xUZ  
    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 c&++[  
    6"GpE5'*  
    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: k mj m6  
    1. 在FRED脚本编辑界面找到参考. xeI{i{8  
    2. 找到Matlab Automation Server Type Library ZYA(Bg^  
        3. 将名字改为MLAPP "7HB3?2>W  
         '!R,)5l0h  
         {UcIt LjY  
    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。 `9ox?|iJ

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Iqsk\2W]a3

    2. 移动探测面对于前一聚焦面的位置。 R*X2Z{n

    4. 在探测面计算照度 ]lUu%<-;  
    5. 使用PutWorkspaceData发送照度数据到Matlab ))`Zv=y"  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 "b 0cj  
    7. 用Matlab画出照度数据 x/=j$oA  
    8. 在Matlab计算照度平均值 !)O$Q}'\  
    9. 返回数据到FRED中 9HX+sB M
