    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。 GZ}*r{  
    =54Vs8.  
    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: [_h.1oZp~  
    enableservice('AutomationServer', true) >J?jr&i  
    enableservice('AutomationServer') +KYxw^k}"7  
    Zt7hzW  
    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 t P At?

    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: y`T--v3mI  
    1. 在FRED脚本编辑界面找到参考. ~&vA_/M  
    2. 找到Matlab Automation Server Type Library D'Jm!Ap  
    3. 将名字改为MLAPP [Ja(ArO3|[

    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。 O>kXysMv>

    现在将脚本代码公布如下,此脚本执行如下几个步骤: V_7 Y1GD  
    1. 创建Matlab服务器。 ~k"eE V p  
    2. 移动探测面对于前一聚焦面的位置。 ID_|H?.  
    3. 在探测面追迹光线 @|jKO5Y  
    4. 在探测面计算照度 e@6RC bj  
    5. 使用PutWorkspaceData发送照度数据到Matlab 7/[TE  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ktkn2Twa/  
    7. 用Matlab画出照度数据 ~Tpe,juG_  
    8. 在Matlab计算照度平均值 w+URCj  
    9. 返回数据到FRED中 3W%f#d$`
