    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。 j1N1c~2  
    )F0 _V 4  
    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: QUaz;kNC7  
    enableservice('AutomationServer', true) U`,&Q ]  
    enableservice('AutomationServer') RV.z xPw>>  
    `4.Wdi-Si  
    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 n>Y3hY  
    5>t&)g  
    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: lN,b@;  
    1. 在FRED脚本编辑界面找到参考. !aeL*`;  
    2. 找到Matlab Automation Server Type Library 7$z")JB  
    3. 将名字改为MLAPP &vj+3<2

    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。 "z69jxXo

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Fla[YWS  
    1. 创建Matlab服务器。 m`g%\o^6i  
    2. 移动探测面对于前一聚焦面的位置。 25l6@7q.  
    3. 在探测面追迹光线 J{@gp,&e  
    4. 在探测面计算照度 Gs7mO  
    5. 使用PutWorkspaceData发送照度数据到Matlab ?Gp~i]  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 `-D6:- ,w  
    7. 用Matlab画出照度数据 vYL{5,t {1  
    8. 在Matlab计算照度平均值 w^ui%9 &6H  
    9. 返回数据到FRED中 Fh? ;,Z
