    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。 n|2-bRK-  
    |3o@I uGt  
    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: zd]L9 _  
    enableservice('AutomationServer', true) yk6UuI^/  
    enableservice('AutomationServer') r>@/XYK&\  
    6U3@-+lF  
    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 Y[]t_o)  
    T0)y5  
    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: qf$|z`c  
    1. 在FRED脚本编辑界面找到参考. < l ^ Z;.  
    2. 找到Matlab Automation Server Type Library 9+|,aG s  
    3. 将名字改为MLAPP 2Yjysn  
     +6-!o,(  
    =W^L8!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。 )O(Gw-jWE

    现在将脚本代码公布如下,此脚本执行如下几个步骤: .HJHJ.Js8X  
    1. 创建Matlab服务器。 &y+*3,!n8  
    2. 移动探测面对于前一聚焦面的位置。 5-po>1g'  
    3. 在探测面追迹光线 @= 9y5r  
    4. 在探测面计算照度 BJr Nbo;T  
    5. 使用PutWorkspaceData发送照度数据到Matlab e-t`\5b;  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 :|Ty 0>k  
    7. 用Matlab画出照度数据 F+r6/e6a  
    8. 在Matlab计算照度平均值 bcs(#  
    9. 返回数据到FRED中 py4_hj\v
