    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。 D+q z`  
    a6It1%a+  
    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: *7L1SjZw  
    enableservice('AutomationServer', true) [`bK {Dq2  
    enableservice('AutomationServer') I9#l2<DYlX  
    WV p6/HS  
    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 l>(*bb1}b

    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: txX>zR*)  
    1. 在FRED脚本编辑界面找到参考. )g]A 'A=  
    2. 找到Matlab Automation Server Type Library -0NkAQrg  
    3. 将名字改为MLAPP d+0= a]

    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。 IfI:|w}:"r

    1. 创建Matlab服务器。 A#i[Us|  
    2. 移动探测面对于前一聚焦面的位置。 g$/7km{TP  
    3. 在探测面追迹光线 fy&u[Jd{  
    4. 在探测面计算照度 ztp2j%'  
    5. 使用PutWorkspaceData发送照度数据到Matlab 6UqDpL7^U  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 KhL%ov  
    7. 用Matlab画出照度数据 Q0ba;KPm
