    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。 2og8VI  
    + $x;FT&  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: A->y#KQ  
    enableservice('AutomationServer', true) Y4B< ]C4  
    enableservice('AutomationServer') -=A W. Z o  
    ttK`*Ng  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 >.-$?2

    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: yw( E}   
    1. 在FRED脚本编辑界面找到参考. GqrOj++>  
    2. 找到Matlab Automation Server Type Library i!=2 8|_  
    3. 将名字改为MLAPP BOQeP/>

    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。 C,!}WB@VME

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ;|Z;YK@20  
    1. 创建Matlab服务器。 s;0eD5b>x  
    2. 移动探测面对于前一聚焦面的位置。 g}-Ch#  
    3. 在探测面追迹光线 OZ$"P<X_"  
    4. 在探测面计算照度 kH43 T  
    5. 使用PutWorkspaceData发送照度数据到Matlab ;|hEXd?b  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 5w#*JK   
    7. 用Matlab画出照度数据 iZy`5  
    8. 在Matlab计算照度平均值 Pj!{j)-tS  
    9. 返回数据到FRED中 jbHk
