    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。 1l)j(,Zd*  
    I__b$  
    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: rd%uc~/  
    enableservice('AutomationServer', true) w2b(,w  
    enableservice('AutomationServer') Zp[>[1@+  
    Pm^FSw"  
    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 ua=7YG

    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: ?m 5"|f\  
    1. 在FRED脚本编辑界面找到参考. @^ta)Ev  
    2. 找到Matlab Automation Server Type Library qF(i1#  
    3. 将名字改为MLAPP /,~]1&?}1  
    <%w TI<m,-  
    vCt][WX(  
    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。 ex~"M&^

    现在将脚本代码公布如下,此脚本执行如下几个步骤: :/SGB3gb1t  
    1. 创建Matlab服务器。 *B@#A4f"  
    2. 移动探测面对于前一聚焦面的位置。 d, i4WKp   
    3. 在探测面追迹光线 Ux^ue9  
    4. 在探测面计算照度 @kDY c8 t9  
    5. 使用PutWorkspaceData发送照度数据到Matlab .EWjeVq  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 #+Bz$CO  
    7. 用Matlab画出照度数据 DU,B  
    8. 在Matlab计算照度平均值 R= Ig !s9  
    9. 返回数据到FRED中 ,@ p4HN*
