    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。  *ni0.  
    64y9.PY  
    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: o5+7Lt]  
    enableservice('AutomationServer', true) 39~WP$GM  
    enableservice('AutomationServer') VY|U B7,C  
    XCgC^c'  
    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 )\W}&9 >

    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: fI.X5c>WK  
    1. 在FRED脚本编辑界面找到参考. 3c:fYE  
    2. 找到Matlab Automation Server Type Library ulEtZ#O{_  
    3. 将名字改为MLAPP VVuNU"-

    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。 Y_XRf8Sw

    4. 在探测面计算照度 >Fe=PRs  
    5. 使用PutWorkspaceData发送照度数据到Matlab FELW?Q?k  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 )"00fZL  
    7. 用Matlab画出照度数据 11!4#z6w
