    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。 *^]  
    11QZ- ^  
    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: sV5k@1Y  
    enableservice('AutomationServer', true) KQ9w>!N[  
    enableservice('AutomationServer') :tFc Pc'  
    UK^w;w2F  
    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 _Fj\0S"  
    x v$fw>  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: vxPr)"Vvz  
    1. 在FRED脚本编辑界面找到参考. rr`_\ut  
    2. 找到Matlab Automation Server Type Library }vB{6E+h/w  
    3. 将名字改为MLAPP "dndhoMq  
    w_`;Mn%p  
    r`FTiPD.C  
    在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 n3V$Xtxw

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ^|h_[>  
    1. 创建Matlab服务器。 z<A8S=s6n  
    2. 移动探测面对于前一聚焦面的位置。 1=+S'_j  
    3. 在探测面追迹光线 j3w~2q"r  
    4. 在探测面计算照度 &~.|9P/45  
    5. 使用PutWorkspaceData发送照度数据到Matlab dQH8s  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 q2B'R   
    7. 用Matlab画出照度数据 c+Z dfdR  
    8. 在Matlab计算照度平均值  K\ pZ  
    9. 返回数据到FRED中 '^7Z]K<v
