    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。 $xT1 1 ^  
    qe?Qeh(!X  
    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: B@ {&<  
    enableservice('AutomationServer', true) 4jQ'+ 2it  
        enableservice('AutomationServer') [>f]@>  
    Z&Ue|Z4Qt  
    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 [F+,YV%t

    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: );Z]SGd  
    1. 在FRED脚本编辑界面找到参考. ;FU|7L$H  
    2. 找到Matlab Automation Server Type Library ?Nf 5w  
        3. 将名字改为MLAPP *:g_'K"+

    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。 A?8\Y{FQ

        6. 使用PutFullMatrix发送标量场数据到Matlab中 dY!u)M;~~  
    7. 用Matlab画出照度数据 <r~wZ}s
