    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。  kZ=yb-~  
    *s?C\)x  
    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: \F<C$cys\  
    enableservice('AutomationServer', true) -pQ0,/}K  
    enableservice('AutomationServer') h_B  nQZ\  
    +u3vKzD  
    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 `eKFs0M.

    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: d6A+pa'2  
    1. 在FRED脚本编辑界面找到参考. |%j7Es  
    2. 找到Matlab Automation Server Type Library &&Otj-n5  
    3. 将名字改为MLAPP @e+qe9A|

    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。 FB O_B

    3. 在探测面追迹光线 )SfM`W)Y  
    4. 在探测面计算照度 =!=DISPo  
    5. 使用PutWorkspaceData发送照度数据到Matlab *s!T$oc  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 9)'wgI#  
    7. 用Matlab画出照度数据 4qyPjAG
