    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。 o^"3C1j  
    i|{nj\6w^  
    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: DMZ aMY|  
    enableservice('AutomationServer', true) Qg$Nj=Cw  
    enableservice('AutomationServer') <RVtLTd/  
    `ur9KP4Dq  
    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 C2|2XL'l(C  
    z2q5f :d8  
    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: ~ 2oP,  
    1. 在FRED脚本编辑界面找到参考. @ZPTf>J}  
    2. 找到Matlab Automation Server Type Library D!T4k]^  
    3. 将名字改为MLAPP 9Kx:^~}20o

    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。 u0KZrz

    现在将脚本代码公布如下,此脚本执行如下几个步骤: v]SE?xF{U  
    1. 创建Matlab服务器。 Z=[a 8CU  
    2. 移动探测面对于前一聚焦面的位置。 FY}*Z=D%  
    3. 在探测面追迹光线 =i>F^7)U1  
    4. 在探测面计算照度 q>4i0p8^  
    5. 使用PutWorkspaceData发送照度数据到Matlab 29657k8  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Q~!hr0 ZR  
    7. 用Matlab画出照度数据 +ENW=N  
    8. 在Matlab计算照度平均值 9<c4y4#y  
    9. 返回数据到FRED中 TZyQOjUu
