    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。 D vkxI<Xa  
    jk~:\8M(A  
    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: |PVt}*0"  
    enableservice('AutomationServer', true) 3eIr{xs  
    enableservice('AutomationServer') TJ@Cjy%  
    x<(b|2qf  
    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 S9sR#  
    w2gf&Lc\  
    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: |VH!)vD  
    1. 在FRED脚本编辑界面找到参考. n(Y%Vmy  
    2. 找到Matlab Automation Server Type Library 3HV%4nZLf  
    3. 将名字改为MLAPP tOdT[&  
    !%L,* '  
    P @% .`8  
    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。 WV<tyx9Z

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ;1AG3P'  
    1. 创建Matlab服务器。 !4#"!Md4o  
    2. 移动探测面对于前一聚焦面的位置。 MEZ{j%-a  
    3. 在探测面追迹光线 'w/qcD-  
    4. 在探测面计算照度 [ .yJV`  
    5. 使用PutWorkspaceData发送照度数据到Matlab M7}Q=q\9  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ~XM[>M\qB  
    7. 用Matlab画出照度数据 T8J4C=?/  
    8. 在Matlab计算照度平均值 _cqy`p@"  
    9. 返回数据到FRED中 Rhgj&4
