    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。 VWf %v  
    :Jxh2  
    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: UTk r.T+2X  
    enableservice('AutomationServer', true) e<\<,)9@/  
    enableservice('AutomationServer') \8b6\qF/\  
    lAASV{s{  
    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 WS0JS'  
    Ex(3D[WmMW  
    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: ;Ss$2V'a  
    1. 在FRED脚本编辑界面找到参考. \2!!L=&4G  
    2. 找到Matlab Automation Server Type Library `~F5 wh~  
    3. 将名字改为MLAPP Tj/GClD:%

    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。 :Ml7G

    4. 在探测面计算照度 }STYG`  
    5. 使用PutWorkspaceData发送照度数据到Matlab < K %j  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 O.+9,4A(  
    7. 用Matlab画出照度数据 Y94MI1O5$  
    8. 在Matlab计算照度平均值 w G!u+
