    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。 hw'2q9J|  
    l9ihW^  
    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: ,< icW &a  
    enableservice('AutomationServer', true) (}}8DB  
        enableservice('AutomationServer') r"[T9  
    Z%{f[|h9}  
    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-=0l)&'D=  
    ?^vZ{B)&0E  
    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: l.W:6", w  
    1. 在FRED脚本编辑界面找到参考. L K~,  
    2. 找到Matlab Automation Server Type Library ZtLn*M  
        3. 将名字改为MLAPP (*x "6)`  
         ^aW[~ c  
         ~=mM/@HD  
    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。 bC{8yV=)

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Mv=cLG?X  
    1. 创建Matlab服务器。 a&hM:n4P  
    2. 移动探测面对于前一聚焦面的位置。 UIj/Id  
    3. 在探测面追迹光线 gAY2|/,  
    4. 在探测面计算照度 {@$3bQ  
    5. 使用PutWorkspaceData发送照度数据到Matlab yMkd|1  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 VC(|t} L4  
    7. 用Matlab画出照度数据 7$=@q|$  
    8. 在Matlab计算照度平均值 \(FDR  
    9. 返回数据到FRED中 K-u/q6ufK
