    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。 u4B,|_MK  
    KC o<%  
    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: !_s|h@  
    enableservice('AutomationServer', true) 4*OL^ \%  
    enableservice('AutomationServer') wJh|$Vn  
    HTI1eLZ2  
    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 i7 `dY {p7  
    V ?3>hQtB  
    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: }[Uh4k8P  
    1. 在FRED脚本编辑界面找到参考. e;pVoRI  
    2. 找到Matlab Automation Server Type Library ]9)pFL  
    3. 将名字改为MLAPP TCp!4-~,  
    m}0US;c#f

    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。 BQ[1,\>

    1. 创建Matlab服务器。 {rGq|Bj  
    2. 移动探测面对于前一聚焦面的位置。 > ZkcL7t9

    4. 在探测面计算照度 -h*Yd)  
    5. 使用PutWorkspaceData发送照度数据到Matlab 6BVV2j)zl:

    7. 用Matlab画出照度数据 g~.,-V}  
    8. 在Matlab计算照度平均值 9}`O*A=KC
