    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。 ki0V8]HP  
    0U/K7sZ  
    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: bk<\ujH  
    enableservice('AutomationServer', true) <D&)OxEn\  
    enableservice('AutomationServer') iV FkYx%}  
    i`/+,<  
    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 FG3UZVUg9

    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: m|=Ecu  
    1. 在FRED脚本编辑界面找到参考. KV|}#<dD  
    2. 找到Matlab Automation Server Type Library -S,ln  
    3. 将名字改为MLAPP ; UiwH

    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。 J`IDlGFYp

    1. 创建Matlab服务器。 q(5j(G ;  
    2. 移动探测面对于前一聚焦面的位置。 B,z<%DAE  
    3. 在探测面追迹光线 P3 c\S[F  
    4. 在探测面计算照度 wdzOFDA
