    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。 ^f@EDG8  
    AuWEy-q?  
    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: ZXp=QH+f  
    enableservice('AutomationServer', true) z`'{l {  
    enableservice('AutomationServer') }O8$?7j(  
    ,zO!`|I  
    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 b1_HDC(

    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: 8M !If  
    1. 在FRED脚本编辑界面找到参考. `N$<]i]s5  
    2. 找到Matlab Automation Server Type Library S)p1[&" M  
    3. 将名字改为MLAPP PY~cu@'k{  
    tK0?9M.)  
    '`^`NI`  
    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。 c?IFI

    1. 创建Matlab服务器。 WF`y j%0  
    2. 移动探测面对于前一聚焦面的位置。 6_rS!X  
    3. 在探测面追迹光线 HOBM?|37CU  
    4. 在探测面计算照度 yKgA"NaM  
    5. 使用PutWorkspaceData发送照度数据到Matlab $3w a%"  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 CB\E@u,  
    7. 用Matlab画出照度数据 Ar,B7-F!  
    8. 在Matlab计算照度平均值 ?u/RQ 1  
    9. 返回数据到FRED中 >Ta|#]{
