    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。 Qqp=  
    Wf&i{3z[  
    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: W)`H(J  
    enableservice('AutomationServer', true) zbDK$g6  
    enableservice('AutomationServer') 4@@gC&:Y  
    Emv9l~mIu  
    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 ~tB9kLFG  
    n&E/{o(  
    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: "g1Fg.o  
    1. 在FRED脚本编辑界面找到参考. sv#/78~|  
    2. 找到Matlab Automation Server Type Library Z}>+!Z  
    3. 将名字改为MLAPP WAVEwA`r

    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。 _2xYDi

    现在将脚本代码公布如下,此脚本执行如下几个步骤: &G7@lz@sK+  
    1. 创建Matlab服务器。 ^C{?LH/2

    3. 在探测面追迹光线 ^ ;cJjl'=  
    4. 在探测面计算照度 -n6T^vf  
    5. 使用PutWorkspaceData发送照度数据到Matlab I! ~3xZ  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 B_0]$D0 ^  
    7. 用Matlab画出照度数据 S{~j5tQv^q  
    8. 在Matlab计算照度平均值 inyS4tb  
    9. 返回数据到FRED中 u6/;=]0
