    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。 f`hyYp`d5  
    }iua] 4 |  
    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: R%b*EBZ  
    enableservice('AutomationServer', true) Jt2,LL:G  
        enableservice('AutomationServer') +z:CZ(fb  
    v}F4R $  
    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 c$Xe.:QY  
    ]~ !X iCqu  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: 3:[!t%Yb  
    1. 在FRED脚本编辑界面找到参考. NZo<IKD$  
    2. 找到Matlab Automation Server Type Library ; .ysCF  
        3. 将名字改为MLAPP 1z~k1usRK  
         IjG5X[@  
         Jo{ zy  
    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。 Hva2j<h

          6R;)  
    现在将脚本代码公布如下,此脚本执行如下几个步骤: \npz .g^c_  
    1. 创建Matlab服务器。 ]u rK$   
    2. 移动探测面对于前一聚焦面的位置。  r=fE8[,  
    3. 在探测面追迹光线 8yE!7$Mj  
    4. 在探测面计算照度 mi7sBA9L8  
    5. 使用PutWorkspaceData发送照度数据到Matlab owE<7TGPI?  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 G*i.a*9<)  
    7. 用Matlab画出照度数据 bK3B3r#$  
    8. 在Matlab计算照度平均值 44|deE3Z  
    9. 返回数据到FRED中 Z0e-W:&;kF
