    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。 (S&X??jfB5  
    M%/ML=eLi  
    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: gmJiKuAL5  
    enableservice('AutomationServer', true) /g< T)$2  
        enableservice('AutomationServer') s>9w+|6Ji  
    .ss/E  
    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 !6'j W!  
    hIuK s5`  
    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: hS OAjS  
    1. 在FRED脚本编辑界面找到参考. X48Q{E+  
    2. 找到Matlab Automation Server Type Library UW8b(b[-6b  
        3. 将名字改为MLAPP S6*3."Sk  
         vHCz_ FV  
         r%}wPN(?D  
    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。 5#!pwjt~7

    现在将脚本代码公布如下,此脚本执行如下几个步骤: HWi0m/J  
    1. 创建Matlab服务器。 Ia*eb%HG  
    2. 移动探测面对于前一聚焦面的位置。 vq B)PL5)  
    3. 在探测面追迹光线 T+8F'9i`  
    4. 在探测面计算照度 JM0'V0z  
    5. 使用PutWorkspaceData发送照度数据到Matlab ZX sm9  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 MS%xOB*6  
    7. 用Matlab画出照度数据 S^]i  
    8. 在Matlab计算照度平均值 Vf`n>  
    9. 返回数据到FRED中 f`*Ip?V-
