    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。 ?,NAihN]  
    Ojs\2('u  
    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: p5KNqqZZ  
    enableservice('AutomationServer', true) %9lxE[/  
    enableservice('AutomationServer') 6PH*]#PfoD  
    tu'MYY  
    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 wB^a1=C  
    e#('`vGB  
    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: 3XRG"  
    1. 在FRED脚本编辑界面找到参考. 4Y!v$r  
    2. 找到Matlab Automation Server Type Library UXP;'  
    3. 将名字改为MLAPP cMv3` $

    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。 1<83MO;

    现在将脚本代码公布如下,此脚本执行如下几个步骤: H[r0jREK  
    1. 创建Matlab服务器。 #t O!3=0  
    2. 移动探测面对于前一聚焦面的位置。 >U)O@W)  
    3. 在探测面追迹光线 ,3j7Y5v  
    4. 在探测面计算照度 =X*E(.6Ip  
    5. 使用PutWorkspaceData发送照度数据到Matlab <Va>5R_d<  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 }#J}8.  
    7. 用Matlab画出照度数据 S\A[Z&k 0  
    8. 在Matlab计算照度平均值 wu')Q/v  
    9. 返回数据到FRED中 UwU]l17~
