    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。 )CyS#j#=  
    GJUL$9  
    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: 6@Y|"b  
    enableservice('AutomationServer', true) !%>7Dw(kt  
        enableservice('AutomationServer') /Q )\+  
    h.fq,em+H  
    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 L4f3X~8,b

    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: }&3 ~|kP~O  
    1. 在FRED脚本编辑界面找到参考. |D.ND%K&  
    2. 找到Matlab Automation Server Type Library Xm 2'6f,  
        3. 将名字改为MLAPP u2[w#

    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。 vcd\GN*4f

        6. 使用PutFullMatrix发送标量场数据到Matlab中 [fIg{Q  
    7. 用Matlab画出照度数据 Ic4H#w
