    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。 HnOF_Twq  
    dW:  
    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: 2{U4wTu  
    enableservice('AutomationServer', true) ~PoGuj2wA  
    enableservice('AutomationServer') 1$Eiv8xd  
    ]^ RgzK  
    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 <JKPtF2b  
     ISq^V  
    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: RKj A`cJ  
    1. 在FRED脚本编辑界面找到参考. 55,vmDd  
    2. 找到Matlab Automation Server Type Library EEkO[J[=  
    3. 将名字改为MLAPP x;b'y4kH  
    ?d_<S0j-)

    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。 >fb*X'Zi%

    现在将脚本代码公布如下,此脚本执行如下几个步骤: }>tUkXlhJ<  
    1. 创建Matlab服务器。 #p_ ~L4iW  
    2. 移动探测面对于前一聚焦面的位置。 7 51\K`L  
    3. 在探测面追迹光线 2V~Yb1P  
    4. 在探测面计算照度 xX|-5cM;  
    5. 使用PutWorkspaceData发送照度数据到Matlab yTZbJx?m  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 [q(7Jv  
    7. 用Matlab画出照度数据 !PQ@"L)p  
    8. 在Matlab计算照度平均值 ?np` RA  
    9. 返回数据到FRED中 PDGh\Y[AK,
