    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。 |fx#KNPf]  
    nwhm[AaNs  
    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: 3JTU^-S<  
    enableservice('AutomationServer', true) S7Qen6lm  
    enableservice('AutomationServer') aam1tm#Q  
    {Qm6?H  
    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 xTGP  
    'H|;%J6d>  
    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: 3b,=  
    1. 在FRED脚本编辑界面找到参考. O.dux5lfBd  
    2. 找到Matlab Automation Server Type Library MwN1]d|6  
    3. 将名字改为MLAPP r,QJG$ Jo  
    py}.00it  
    dy'X<o^?W  
    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。 Y7*'QKz2

    现在将脚本代码公布如下,此脚本执行如下几个步骤: t7sUtmq  
    1. 创建Matlab服务器。 ]j72P  
    2. 移动探测面对于前一聚焦面的位置。 )H.ubM1  
    3. 在探测面追迹光线 r*c82}tc  
    4. 在探测面计算照度 \ YjB+[.  
    5. 使用PutWorkspaceData发送照度数据到Matlab 4S^  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ,HQ1C8  
    7. 用Matlab画出照度数据 h 3eGq:!9  
    8. 在Matlab计算照度平均值 e=0l<Rj  
    9. 返回数据到FRED中 S83]O!w0
