    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。 5!C_X5M  
    >vrxP8_  
    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: *'"T$ib  
    enableservice('AutomationServer', true) k{tMzx]F__  
    enableservice('AutomationServer') )CI1;  
    ,U*)2`[  
    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 |8%m.fY`

    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: &`Y!;@K9W#  
    1. 在FRED脚本编辑界面找到参考. Vh3Ijn  
    2. 找到Matlab Automation Server Type Library 2;L|y._`w  
    3. 将名字改为MLAPP E^_w I>

    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。 41#w|L \

    1. 创建Matlab服务器。 wn Y$fT9  
    2. 移动探测面对于前一聚焦面的位置。 j4FeSGa  
    3. 在探测面追迹光线 , "jbq~  
    4. 在探测面计算照度 *?QE2&S:  
    5. 使用PutWorkspaceData发送照度数据到Matlab :ztr)  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 rOW-0B+N  
    7. 用Matlab画出照度数据 JB</euyV  
    8. 在Matlab计算照度平均值 dAP|:&y@
