    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。 jA?[*HB  
    VB  |k  
    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: vh"';L_*37  
    enableservice('AutomationServer', true) q*R~gEi#yk  
    enableservice('AutomationServer') v,ecNuy*d  
    rMWvW(@@D  
    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 +,"[0RH  
    jo"+_)]  
    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: < hy!B4  
    1. 在FRED脚本编辑界面找到参考. &/uakkS  
    2. 找到Matlab Automation Server Type Library qDswFs(  
    3. 将名字改为MLAPP 'p[6K'Uq5

    !V#*(_+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。 Kc r)W

    5. 使用PutWorkspaceData发送照度数据到Matlab vQXF$/S  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 |#*+#27
