    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。 i-Z@6\/a5  
    q*T+8 O  
    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: `s+qz  
    enableservice('AutomationServer', true) b~|B(lL6Xm  
    enableservice('AutomationServer') -*WD.|k  
    6};Sn/ 8  
    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 h'bxgIl'`  
    .RT5sj\d  
    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: -~5yl}  
    1. 在FRED脚本编辑界面找到参考. ScI9.{  
    2. 找到Matlab Automation Server Type Library R_^:<F0  
    3. 将名字改为MLAPP XdB8Oj~~

    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。 m$4Gm(Up

    现在将脚本代码公布如下,此脚本执行如下几个步骤: {{O1C ~  
    1. 创建Matlab服务器。 qn<~ LxQ  
    2. 移动探测面对于前一聚焦面的位置。 "e(N h%t  
    3. 在探测面追迹光线 |OC6yN *P)  
    4. 在探测面计算照度 Gf"/fpeQx  
    5. 使用PutWorkspaceData发送照度数据到Matlab ?e BN_a,r6  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ^v,^.>P  
    7. 用Matlab画出照度数据 ci$o~b6V  
    8. 在Matlab计算照度平均值 \Wo,^qR  
    9. 返回数据到FRED中 Q{>{ e3z}
