    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。 "9QZX[J|*  
    !o?&{"#+  
    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: )R'%SLw  
    enableservice('AutomationServer', true) K\fD';  
    enableservice('AutomationServer') jN*wbqL  
    .[1 f$  
    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 U5~aG!E

    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: +>*=~R  
    1. 在FRED脚本编辑界面找到参考. )AR- b8..o  
    2. 找到Matlab Automation Server Type Library Tsb}\  
    3. 将名字改为MLAPP \#Jq%nd

    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。 '/6f2[%Y"

    4. 在探测面计算照度 .$W}  
    5. 使用PutWorkspaceData发送照度数据到Matlab $/g`{O I]K  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 gzSm=6Qw0  
    7. 用Matlab画出照度数据 RHNAHw9  
    8. 在Matlab计算照度平均值 LiQH!yHW  
    9. 返回数据到FRED中 [hg9 0Q6
