    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。 YR>xh2< 9  
    5 X rn]  
    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: xo}hu %XL  
    enableservice('AutomationServer', true) )DW;Gc  
        enableservice('AutomationServer') Mh\c+1MFs  
    G9]GK+@&F  
    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 E;SF f

    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: ;iWCV& >w  
    1. 在FRED脚本编辑界面找到参考. U3>G9g>^B  
    2. 找到Matlab Automation Server Type Library 3i<*,@CY  
        3. 将名字改为MLAPP zB4gnVhus|

         MC3{LVNK  
    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。 :DEZ$gi

    1. 创建Matlab服务器。 JyV"jL   
    2. 移动探测面对于前一聚焦面的位置。 :(Gg]Z9^8  
    3. 在探测面追迹光线 "{}5uth  
    4. 在探测面计算照度 1*s Lj#  
    5. 使用PutWorkspaceData发送照度数据到Matlab Y0DBkg  
        6. 使用PutFullMatrix发送标量场数据到Matlab中  z>!b  
    7. 用Matlab画出照度数据 &WIPz\  
    8. 在Matlab计算照度平均值 -Rmz`yOq}  
    9. 返回数据到FRED中 K=;p^dE
