    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。 hsZ/Vnn`  
    wT1s;2%  
    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: 8`Ya7c>  
    enableservice('AutomationServer', true)  >@ t  
        enableservice('AutomationServer') U$rMZk  
    2ZH+fV?.  
    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 taQE r 2Zy

    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: DL]tg [w{  
    1. 在FRED脚本编辑界面找到参考. v9$!v^U"D  
    2. 找到Matlab Automation Server Type Library H=r-f@EOrI  
        3. 将名字改为MLAPP {|;a?] ?

         8xpplo8  
    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。 wBPo{

    2. 移动探测面对于前一聚焦面的位置。 jvT'N@  
    3. 在探测面追迹光线 D$>_W,*V  
    4. 在探测面计算照度 3Ob.OwA  
    5. 使用PutWorkspaceData发送照度数据到Matlab sdu?#O+c1  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 Fsx?(?tCMo  
    7. 用Matlab画出照度数据 u8e_Lqx?  
    8. 在Matlab计算照度平均值 BFLef3~.0  
    9. 返回数据到FRED中 'J|2c;M\x
