    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。 GqIvvnw@f  
    '&pf  
    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: *&hXJJ[+  
    enableservice('AutomationServer', true) ^EuyvftZ  
    enableservice('AutomationServer') H4y1Hpa,  
    F)E7(Un`8  
    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 .kB3jfw0,

    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: _ntW}})K  
    1. 在FRED脚本编辑界面找到参考. *xv/b=  
    2. 找到Matlab Automation Server Type Library 9?}rpA`P  
    3. 将名字改为MLAPP * 0&i'0>

    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。 +}(B856+

    现在将脚本代码公布如下,此脚本执行如下几个步骤: /ie3H,2  
    1. 创建Matlab服务器。 Iu1Sj`A  
    2. 移动探测面对于前一聚焦面的位置。 }lNuf u  
    3. 在探测面追迹光线 H%NLL4&wu  
    4. 在探测面计算照度  ,3@15j  
    5. 使用PutWorkspaceData发送照度数据到Matlab Yyo9{4v+p{  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 n7,6a  
    7. 用Matlab画出照度数据 ~\)&{ '  
    8. 在Matlab计算照度平均值 u6qi  
    9. 返回数据到FRED中 uu@'02G8
