    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。 nB|m!fi<  
    IPVD^a ?  
    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: U } K]W>Z  
    enableservice('AutomationServer', true) 'K!u}py  
    enableservice('AutomationServer') p2=+cS"HC  
    >s%&t[r6  
    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 L*(!P4S%}

    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: ov 'g'1}  
    1. 在FRED脚本编辑界面找到参考. VYo2m  
    2. 找到Matlab Automation Server Type Library (r9W[  
    3. 将名字改为MLAPP 2Wx~+@1y

    O0Pb"ou_h.  
    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。 S^c; i

    5. 使用PutWorkspaceData发送照度数据到Matlab NI^jQS M]  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 oc>N| ww:  
    7. 用Matlab画出照度数据 6JB* brO
