    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。 aJ[|80U  
    }taG/kE62  
    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: B/Ltb^a  
    enableservice('AutomationServer', true) YR[I,j  
    enableservice('AutomationServer') cGlpJ)'-{  
    c7nbHJi  
    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  vSo1WS  
    [EK@f,iM  
    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: FJB B@<>:  
    1. 在FRED脚本编辑界面找到参考. vVSf'w   
    2. 找到Matlab Automation Server Type Library hfg ^z5  
    3. 将名字改为MLAPP H;#C NB<e  
    2I 7|hZ,  
    %q6I-  
    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。  3CPSyF

    现在将脚本代码公布如下,此脚本执行如下几个步骤: KGmAnN  
    1. 创建Matlab服务器。 a3,A_M}M'  
    2. 移动探测面对于前一聚焦面的位置。 #VxN [770  
    3. 在探测面追迹光线 z G`|)  
    4. 在探测面计算照度 `rV -,-r@  
    5. 使用PutWorkspaceData发送照度数据到Matlab B_RF)meux  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 <@c@`K  
    7. 用Matlab画出照度数据 7Dw. 9EQ  
    8. 在Matlab计算照度平均值 AEUR` .  
    9. 返回数据到FRED中 0 c ]]
