    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。 mCEWp  
    4?~Ei[KgQn  
    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: SSr2K  
    enableservice('AutomationServer', true) Y1 6pT  
    enableservice('AutomationServer') Mm#=d?YUHJ  
    q<A,S8'm  
    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 rXnG"A

    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: _2Fa .gi  
    1. 在FRED脚本编辑界面找到参考. 90+Hv:wF  
    2. 找到Matlab Automation Server Type Library %l)~C%T  
    3. 将名字改为MLAPP M,N(be-

    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。 +F6R@@rWr

    现在将脚本代码公布如下,此脚本执行如下几个步骤: m{0u+obi&w  
    1. 创建Matlab服务器。 7:&a,nU  
    2. 移动探测面对于前一聚焦面的位置。 pPZ^T5-ks  
    3. 在探测面追迹光线 )hK1W\5  
    4. 在探测面计算照度 ~sc@49p  
    5. 使用PutWorkspaceData发送照度数据到Matlab OTwXc*2u]  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 &bS!>_9  
    7. 用Matlab画出照度数据 eR5+1b  
    8. 在Matlab计算照度平均值 &E8fd/s= k  
    9. 返回数据到FRED中 y1hJVYE2
