    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。 `O=;E`ep  
    Kc[u} .U  
    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: cNr][AzU@  
    enableservice('AutomationServer', true) pt cLJ]+)  
        enableservice('AutomationServer') :/[YY?pg-  
    q uGPk)c  
    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 kw^Dp[8X  
    /-YlC (kL  
    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: Wx|6A#cg!  
    1. 在FRED脚本编辑界面找到参考. Zc3:9   
    2. 找到Matlab Automation Server Type Library Px7g\[]  
        3. 将名字改为MLAPP xFm{oJ!]&

         lcT+$4zk.  
    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。 ROt0<^<

    1. 创建Matlab服务器。 ):fu   
    2. 移动探测面对于前一聚焦面的位置。 ~sHZh  
    3. 在探测面追迹光线 "">fn(  
    4. 在探测面计算照度 )|h;J4V  
    5. 使用PutWorkspaceData发送照度数据到Matlab wz0$g4  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 ({_:^$E\  
    7. 用Matlab画出照度数据 Sp~Gv>uMK  
    8. 在Matlab计算照度平均值 t6%xit+  
    9. 返回数据到FRED中 h>^jq{yu
