    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。 P &._ -[  
    u^[v{hv'H  
    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: _n gMC]-T  
    enableservice('AutomationServer', true) 73`UTXvWU  
    enableservice('AutomationServer') uV:;y}T^Z  
    q|2C>{8  
    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 jX,~iZ_B  
    6&T1 ZY`  
    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: " <AljgF  
    1. 在FRED脚本编辑界面找到参考. =Z$6+^L  
    2. 找到Matlab Automation Server Type Library U#4W"1~iX  
    3. 将名字改为MLAPP =w>QG{-N

    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。 a{,t@G

    3. 在探测面追迹光线 RwKN  
    4. 在探测面计算照度 ;_ton?bF

    6. 使用PutFullMatrix发送标量场数据到Matlab中 8hT>)WH}wo  
    7. 用Matlab画出照度数据 iiscm\
