    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。 7TA&u'  
    7=HpEc  
    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: \cQ+9e)  
    enableservice('AutomationServer', true) {<Xl57w-Q  
    enableservice('AutomationServer') nbBox,zW  
    2,p= %  
    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 3m"9q  
    }BiA@n,  
    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: !X1 KOG  
    1. 在FRED脚本编辑界面找到参考. Lt {&v ^y  
    2. 找到Matlab Automation Server Type Library MpJ]1  
    3. 将名字改为MLAPP JQSczE3

    W\O.[7JP  
    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。 &7KX`%K"D

    现在将脚本代码公布如下,此脚本执行如下几个步骤: AZnFOS  
    1. 创建Matlab服务器。 :V#B]:Z9  
    2. 移动探测面对于前一聚焦面的位置。 ,9W!cD+0  
    3. 在探测面追迹光线 gh% Q9Ni-  
    4. 在探测面计算照度 D"P<;@ef  
    5. 使用PutWorkspaceData发送照度数据到Matlab ;MW=F9U*  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Sv[+~co<l  
    7. 用Matlab画出照度数据 QLZ%m$Z  
    8. 在Matlab计算照度平均值 -IL' (vx  
    9. 返回数据到FRED中 =64Ju Wvo
