    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。 @'n07 5)h  
    fk%W0 7x!  
    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: E,IeW {6s  
    enableservice('AutomationServer', true) `%S 35x9  
    enableservice('AutomationServer') 3 UUOB.  
    NzS(, F  
    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 ]M3V]m  
    D!7-(3R  
    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: ? nx3# <  
    1. 在FRED脚本编辑界面找到参考. x -;tV=E}  
    2. 找到Matlab Automation Server Type Library 0b=1Ce+0q  
    3. 将名字改为MLAPP (|O9L s7N

    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。 Cp"a,%b6u

    2. 移动探测面对于前一聚焦面的位置。 Ymvd3>_  
    3. 在探测面追迹光线 tuK2D,6  
    4. 在探测面计算照度 f4'WT  
    5. 使用PutWorkspaceData发送照度数据到Matlab N!~O~ Eo3  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 _c!$K#Yl{  
    7. 用Matlab画出照度数据 Nyx)&T&I  
    8. 在Matlab计算照度平均值 6W\G i>  
    9. 返回数据到FRED中 =D~>$ Y
