    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。 YX18!OhQ  
    zvdtP'&uj  
    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: %1@+pf/  
    enableservice('AutomationServer', true) +MGEO+  
    enableservice('AutomationServer') -2K`:}\y&  
    h/V0}|b  
    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 ZR6KE_  
    $?(fiFC  
    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: f`RcfYt  
    1. 在FRED脚本编辑界面找到参考. t 4{{5U'\  
    2. 找到Matlab Automation Server Type Library Xko[Z;4v8'  
    3. 将名字改为MLAPP P[8`]=

    "npj%O<bd  
    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。 OY51~#BF

    5. 使用PutWorkspaceData发送照度数据到Matlab H^B/ '#mO  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 xQm!  
    7. 用Matlab画出照度数据 6S2D\Bt,_
