    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。 Q)H1\  
    G T3wJQ5N  
    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: r=`]L-}V  
    enableservice('AutomationServer', true) W{{{c2 .  
    enableservice('AutomationServer') ]xYm@%>6  
    NY& |:F  
    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 Gp PlO]  
    `4&a"`&$  
    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: 5W(S~}  
    1. 在FRED脚本编辑界面找到参考. WN_i-A1G/h  
    2. 找到Matlab Automation Server Type Library _ i-(` 5  
    3. 将名字改为MLAPP E>|xv#:~DV

    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。 \N?,6;%xB

    2. 移动探测面对于前一聚焦面的位置。 H=f'nm]dQ  
    3. 在探测面追迹光线 U'Xw'?Uj  
    4. 在探测面计算照度 rl <! h5  
    5. 使用PutWorkspaceData发送照度数据到Matlab 7n_'2qY  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ub#>kCL9  
    7. 用Matlab画出照度数据 HLP nbI-+  
    8. 在Matlab计算照度平均值 IO(Y_7  
    9. 返回数据到FRED中 E@f2hW2
