    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。 0u'qu2mV  
    l[EjtN  
    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: mtON dI  
    enableservice('AutomationServer', true) ~<, QxFG5  
    enableservice('AutomationServer') +s'qcC  
    tsA+B&R_]  
    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 2"~QI xY=

    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: G} &{]w@  
    1. 在FRED脚本编辑界面找到参考. e:~r_,K  
    2. 找到Matlab Automation Server Type Library kr C4O2Fkj  
    3. 将名字改为MLAPP $rh{f<  
    -&ic%0|f

    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。 fiq4|!^h

    现在将脚本代码公布如下,此脚本执行如下几个步骤: WYb\vm =r  
    1. 创建Matlab服务器。 ?1?zma S  
    2. 移动探测面对于前一聚焦面的位置。 /@<Pn&Rq  
    3. 在探测面追迹光线 +hIStA  
    4. 在探测面计算照度 bJo)rM :m  
    5. 使用PutWorkspaceData发送照度数据到Matlab \V#2K><  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Qw{LD+r(  
    7. 用Matlab画出照度数据 .#,!&Lt
