    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。 en/h`h]h  
    cIQbu#[@  
    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: ?A3u2-  
    enableservice('AutomationServer', true) |h%HUau  
    enableservice('AutomationServer') tSux5 yV  
    # S/n3  
    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 3~7!=s\v

    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: "G~!J\  
    1. 在FRED脚本编辑界面找到参考. Trs2M+r)  
    2. 找到Matlab Automation Server Type Library /qJCp![X  
    3. 将名字改为MLAPP )HC/J-  
    O$;#GpR  
    }!{R;,5/n  
    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。 {]cr.y]\

    4. 在探测面计算照度 >e& L"  
    5. 使用PutWorkspaceData发送照度数据到Matlab i NfAn&  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 `"[qb ?z  
    7. 用Matlab画出照度数据 -b{<VrZ
