    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。 k^I4z^O=-;  
    SZJ~ktXC-V  
    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: =g' 7 xA  
    enableservice('AutomationServer', true) V/i&8UMw  
    enableservice('AutomationServer') s$xctIbm?,  
    *=}$@O S  
    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 N,|:=gD_  
    Y}(#kqh>  
    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: '/ 3..3k  
    1. 在FRED脚本编辑界面找到参考. eG26m_S=  
    2. 找到Matlab Automation Server Type Library u#XNl":x  
    3. 将名字改为MLAPP 0hcrQ^BB!b

    s9) @$3\  
    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*s

    1. 创建Matlab服务器。 7QL>f5Q  
    2. 移动探测面对于前一聚焦面的位置。 [r_,BH\nu  
    3. 在探测面追迹光线 3EB8ls2  
    4. 在探测面计算照度 k!O#6Z  
    5. 使用PutWorkspaceData发送照度数据到Matlab I"*g-ji0  
    6. 使用PutFullMatrix发送标量场数据到Matlab中  ~d_Z?Z  
    7. 用Matlab画出照度数据 uy{mSx?td  
    8. 在Matlab计算照度平均值 %*]3j^b Q+  
    9. 返回数据到FRED中 2;.7c+r0
