    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。 ?v-1zCls  
    cMzkL%  
    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: {FI\~ q  
    enableservice('AutomationServer', true) 8)VgS &B~  
    enableservice('AutomationServer') u7;~  
    <fdPLw;@e4  
    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 QI_59f>

    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: U4Nh  
    1. 在FRED脚本编辑界面找到参考. htPqT,L  
    2. 找到Matlab Automation Server Type Library _iE j  
    3. 将名字改为MLAPP r Db>&s3

    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。 {?{U,&

    现在将脚本代码公布如下,此脚本执行如下几个步骤: -iCcoA  
    1. 创建Matlab服务器。 9zgNjjCl]  
    2. 移动探测面对于前一聚焦面的位置。 :o"8MZp  
    3. 在探测面追迹光线 )uP[!LV[e  
    4. 在探测面计算照度 L<(VG{)Z  
    5. 使用PutWorkspaceData发送照度数据到Matlab P.sgRsL  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 9YF$CXonE=  
    7. 用Matlab画出照度数据 Ewo*yY>  
    8. 在Matlab计算照度平均值 NfE.N&vI_c  
    9. 返回数据到FRED中 D*vm cSf
