    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。 ]dq5hkjpU  
    jM]d'E?ZLA  
    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: #K|0lau l  
    enableservice('AutomationServer', true)  +tIz[+u  
        enableservice('AutomationServer') 3|zgDA  
    Qo.Uqz.C  
    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 o*-9J2V=J  
    vu<#wW*9  
    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: L@nebT;\'  
    1. 在FRED脚本编辑界面找到参考. 4#_$@ r  
    2. 找到Matlab Automation Server Type Library Q70bEHLA  
        3. 将名字改为MLAPP jQ?LHUE

    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。 gJh}CrU-

    4. 在探测面计算照度 wdwp9r

        6. 使用PutFullMatrix发送标量场数据到Matlab中 N xFUO0O3  
    7. 用Matlab画出照度数据 1[s0Lz  
    8. 在Matlab计算照度平均值 g_vm&~U/'  
    9. 返回数据到FRED中 Tm_8<$ 7
