    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。 [kyIF\0  
    aoVfvz2Y  
    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: VsM~$ )  
    enableservice('AutomationServer', true) &;Jg2f%.  
    enableservice('AutomationServer') u =%1%p,  
    bs=x>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 Sr?2~R0&

    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: ^9*kZV<K  
    1. 在FRED脚本编辑界面找到参考. a8laP N  
    2. 找到Matlab Automation Server Type Library VwrHD$  
    3. 将名字改为MLAPP B)}.%G*

    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。 R-V4Ju[:

    3. 在探测面追迹光线 hY S}PE  
    4. 在探测面计算照度 )D"E]  
    5. 使用PutWorkspaceData发送照度数据到Matlab txp^3dZ`^  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 9#X"m,SB  
    7. 用Matlab画出照度数据 [uD G;We=  
    8. 在Matlab计算照度平均值 :sL?jGk\  
    9. 返回数据到FRED中 78fFAN`
