    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。 $ A-b vL  
    -Ubj6 t_K  
    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: mKg@W;0ML  
    enableservice('AutomationServer', true) R+$8w2#  
    enableservice('AutomationServer')  i j&p4  
    s"0b%0?A  
    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_ zA  
    l@d gJ  
    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: %XXkVK`  
    1. 在FRED脚本编辑界面找到参考. f@:CyB GQ  
    2. 找到Matlab Automation Server Type Library {B yn{?w  
    3. 将名字改为MLAPP {.#zHL ;  
    %N~C vN@T  
    DB&SOe  
    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。 ,bSVVT-b

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ~Y/z=^  
    1. 创建Matlab服务器。 <~%t$:  
    2. 移动探测面对于前一聚焦面的位置。 2Yyb#Ow  
    3. 在探测面追迹光线 o*7yax  
    4. 在探测面计算照度 gB CC  
    5. 使用PutWorkspaceData发送照度数据到Matlab = ?N^>zie  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Ww87  
    7. 用Matlab画出照度数据 T=? bdIl  
    8. 在Matlab计算照度平均值 u"F;OT\>g  
    9. 返回数据到FRED中 *=^[VV!
