    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。 R%%h=]  
    oIY@xuj  
    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: ')v<MqBr  
    enableservice('AutomationServer', true) 8IihG \  
    enableservice('AutomationServer') 0o&c8?@j  
    [YQ` `  
    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 'ul~f$ V  
    @I0[B<,:G  
    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: E{Y)=tW[  
    1. 在FRED脚本编辑界面找到参考. $x1PU67  
    2. 找到Matlab Automation Server Type Library <nT).S>+  
    3. 将名字改为MLAPP .Vb\f  
    3ES3, uR  
    gPM<LO`;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。 4>8'.8S

    1. 创建Matlab服务器。 d"4J)+q  
    2. 移动探测面对于前一聚焦面的位置。 g:>Mooxzi  
    3. 在探测面追迹光线 N[dv  
    4. 在探测面计算照度 &o*f*(C2  
    5. 使用PutWorkspaceData发送照度数据到Matlab R4g% $}  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 >c 5V VA8  
    7. 用Matlab画出照度数据 {nlqQ.jO  
    8. 在Matlab计算照度平均值 x3?:"D2
