    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。 +w5?{J  
    R[t[M}q  
    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: \ed(<e>  
    enableservice('AutomationServer', true) *k$&Hcr$  
        enableservice('AutomationServer') Q+dI,5YF  
    _v,n~a}&  
    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 = ByW`  
    ?H?r!MZ%  
    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: DdgFBO  
    1. 在FRED脚本编辑界面找到参考. Q4*cL5j  
    2. 找到Matlab Automation Server Type Library UW3F)  
        3. 将名字改为MLAPP )]R8 $S  
         q<7n5kJ~  
         z{x -Vfd  
    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。 v0sX'>f

    1. 创建Matlab服务器。 j!dklQh0  
    2. 移动探测面对于前一聚焦面的位置。 70~]J8T+u  
    3. 在探测面追迹光线 N~(}?'y9S  
    4. 在探测面计算照度 |/$#G0X;H  
    5. 使用PutWorkspaceData发送照度数据到Matlab 7;{F"/A  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 jF8ld5|_|  
    7. 用Matlab画出照度数据 ImVe 71mh  
    8. 在Matlab计算照度平均值 [R$4n-$  
    9. 返回数据到FRED中 5KzU&!Zh9
