    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。 32GI+NN  
    mR}8}K]L  
    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: b:1B >  
    enableservice('AutomationServer', true) [*%lm9 x  
    enableservice('AutomationServer') T! }G51  
    <Qq {&,Le  
    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 /Pjd"

    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: "jZZ>\  
    1. 在FRED脚本编辑界面找到参考. {/[@uMS_6]  
    2. 找到Matlab Automation Server Type Library O"9t,B>=i  
    3. 将名字改为MLAPP g5BL"Dn

    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。 %6ckau1_;

    现在将脚本代码公布如下,此脚本执行如下几个步骤: pbzt8 P[  
    1. 创建Matlab服务器。 Y58H.P  
    2. 移动探测面对于前一聚焦面的位置。  ;LS.  
    3. 在探测面追迹光线 ^P^"t^O  
    4. 在探测面计算照度 _ $PeFE2  
    5. 使用PutWorkspaceData发送照度数据到Matlab rEr=Mi2  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ^%oH LsY9  
    7. 用Matlab画出照度数据 Hc/7x).  
    8. 在Matlab计算照度平均值 2e6P?pX~2  
    9. 返回数据到FRED中 6>?qBWW
