    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。 K.n #;|  
    k`6T% [D]  
    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: DF/p{s1Y3  
    enableservice('AutomationServer', true) hVI $r  
    enableservice('AutomationServer') eP$0TDZ  
    dy;Ue5  
    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 \ aQBzEX

    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: J (Yfup  
    1. 在FRED脚本编辑界面找到参考. cOth q87:  
    2. 找到Matlab Automation Server Type Library CE:TQzg  
    3. 将名字改为MLAPP !9DqW&8

    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。 IY?[0S

    2. 移动探测面对于前一聚焦面的位置。 h #Od tc1)  
    3. 在探测面追迹光线 eyy{z;D8r  
    4. 在探测面计算照度 deHhl(U;  
    5. 使用PutWorkspaceData发送照度数据到Matlab k!b\qS~Q  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 .a1WwI  
    7. 用Matlab画出照度数据 Tk9u+;=6$  
    8. 在Matlab计算照度平均值 ^[Cpu_]D  
    9. 返回数据到FRED中 9%j_"+<c
