    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。 :L,]<n  
    4(NI-|q0  
    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: S1."2AxO  
    enableservice('AutomationServer', true) 4b)xW&K{  
    enableservice('AutomationServer') @)}U\=  
    `#hy'S:e  
    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 1EN5ZN,  
    ,=FYf|Z  
    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: .|K5b]na  
    1. 在FRED脚本编辑界面找到参考. R)v`ZF,/b  
    2. 找到Matlab Automation Server Type Library &nq[Vy0kO4  
    3. 将名字改为MLAPP @0G} Q  
    +=O:z *O  
    Ur@3_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。 R9HRbVBJf

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ;-3M  
    1. 创建Matlab服务器。 `JC!uc  
    2. 移动探测面对于前一聚焦面的位置。 WJ%b9{<  
    3. 在探测面追迹光线 N4Ym[l  
    4. 在探测面计算照度 @[^H*^1|g  
    5. 使用PutWorkspaceData发送照度数据到Matlab [4gv_g  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 9X-DR  
    7. 用Matlab画出照度数据 =J:~AD#  
    8. 在Matlab计算照度平均值 w v1R ]3}  
    9. 返回数据到FRED中 lm+wjhkN
