    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。 dWUm\t'#  
    oe |)oTv  
    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: !^=*Jq>  
    enableservice('AutomationServer', true) (k) l= ]`}  
    enableservice('AutomationServer') g-H N  
    ,5kKimTt  
    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 =/Mq5.

    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: t2"O  
    1. 在FRED脚本编辑界面找到参考. m-*i>4;  
    2. 找到Matlab Automation Server Type Library P'*)\faw  
    3. 将名字改为MLAPP D 38$`j  
    EB=-H#  
    TI#''XCB5  
    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。 "B4;,+4kR

    4. 在探测面计算照度 Rhz_t@e  
    5. 使用PutWorkspaceData发送照度数据到Matlab zj`v?#ET  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 c^u"I'#Q  
    7. 用Matlab画出照度数据 B}?5]N==]  
    8. 在Matlab计算照度平均值 'wI"Bo6e
