    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。 d<Q%h?E  
    Hv,ll1@h  
    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: js <Up/1  
    enableservice('AutomationServer', true) `pZX!6Wn  
    enableservice('AutomationServer') qAH^BrJ  
    uK"FopUJ4i  
    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 wLqj<ot  
    S qb>a j  
    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: n9={D  
    1. 在FRED脚本编辑界面找到参考. KhB775  
    2. 找到Matlab Automation Server Type Library Q. O4R_H  
    3. 将名字改为MLAPP O$m &!J  
    xi "3NF%=  
    Kd+E]$F_OH  
    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。 sfn^R+x4,9

    现在将脚本代码公布如下,此脚本执行如下几个步骤: klFS3G  
    1. 创建Matlab服务器。 i) X~L4gn  
    2. 移动探测面对于前一聚焦面的位置。 f*Q9u>1p  
    3. 在探测面追迹光线 7:uz{xPK6  
    4. 在探测面计算照度 7R:Ij[dV  
    5. 使用PutWorkspaceData发送照度数据到Matlab U{oM*[  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ( s4W&  
    7. 用Matlab画出照度数据 @- |G_BZ  
    8. 在Matlab计算照度平均值 `j)56bR  
    9. 返回数据到FRED中 @XzfuuE]
